For Constipation "IT WORKS, I PROMISE!!!! Ok, so my doctor told me to drink one 10 oz bottle of magnesium citrate at 4 PM this afternoon to empty my bowels before my hysterectomy in the morning. She said if the first one didn’t work, drink another one around 8 PM. Ok, so I drank the one at 4 PM. I swear, I have never had such awful stomach cramps! That was it though. So 8 PM comes around. I drink the second bottle. 15 minutes later, I was having diarrhea so explosive and forceful that I was preparing myself for lift-off to be launched into another galaxy somewhere deep into outer space. I’ll tell you what, if you ever have any constipation problems this stuff will fix it for you! As I mentioned above, I’m going in for a hysterectomy in the morning, but now? I’m wondering if I need to go in for anal reconstruction. This stuff is potent, y’all! If you plan on drinking this, don’t make any plans because you will be cemented to the toilet until your great-great-great grandkids graduate college!"

For Constipation "One word: Peepoo. I used Mag citrate for colonoscopy prep. 3 minutes after downing the entire bottle, I thought 'hmm, I should have prepared more.' My kids are in the bath still, having no idea I would be almost throwing them out the door. I wasn't fast enough for the first one, so I closed the shower curtain and proceeded to shake the house with what can only be described as a minor earthquake. I turned the tap on and coughed as loudly as I could to try and mitigate the jet engine decibel sound emanating from my butt, but we all knew what was happening. I gave up on leaving my perch, so I got my laptop and planted myself for the foreseeable future. 2 episodes of a crappy Netflix show and 300 experience points on Duolingo before it was safe to poke my head out again. Word to the wise: Prepare! and if you don't have to drink the whole bottle, just don't! Plus side, I can now explain my experience in French. La diarrhée n'est pas un mot assez gross pour décrire ce qui va vous arriver."

For Constipation "I hadn’t pooped in about a week. I wasn’t uncomfortable but I knew I was full of poop. I have taken this before and when I was in this situation, so I decided to do it again. I am 105 lbs and drank the whole bottle. (Last time I drank half) Big mistake. HUGE mistake. I took it at 5 pm and didn’t start to go until almost midnight. I was running back and forth to brown town until 2:30 am. Thought my body evicted every evil piece of poop from my colon. I was wrong. I woke up at 6 am and my butthole was puckering while my stomach was yelling. I ran to the toilet, once again and eliminated what I hope was the baby food I ate when I was 8 months old. Thought that was over. WRONG. I kept going!! How in the world is there anything left in me? I’ve gone 3 more times since I started this review. I mean, it works but I’m afraid to leave the house. Last time I took half, I'd like to know why I drank the whole bottle. My butt hurts and I’m pooping again."

For Constipation "Only use this as a last resort, it’s some intense stuff. It’s been over 24 hours and I’m still feeling the effects. I’m exhausted and tired of my stomach feeling the way it does. I highly recommend getting diaper rash cream, because you’ll most likely need it. Do not, unless told by your doctor, take a whole bottle of this stuff, it’s been one of the worst experiences of all my 20 years."

For Constipation "Holy guacamole Batman, it worked! But boy, it was a journey, lol! For 4 days, I hadn't pooped! I had already taken laxatives, stool softener, a bucket of prunes, fiber pills, other fiber pills, and still no poop over the last 4 days! So, I called a friend that has Gastroparesis and asked her what she takes? She said MC! So, here it is 7:30 at night, and I'm off to the drugstore. I chugged it at 8:43. I immediately wanted to puke after I was done. But I said no to myself, I have to keep this down! I managed to get down another bottle of water in addition to the two bottles of water I drank before the MC! So, I'm sitting here on the potty reading all the other stories and laughing so hard I should have crapped my pants but nope! No poop! An hour later, I managed to make it to my bed. It's 9:45 pm, insanely nauseated (I gave up on pushing, even though I had the urge to), hoping I can just nap, then I won't feel the sickness! Then I get this cold sweat come over me, my hands get all clammy, my head starts hurting, I feel like my heart is about to pop out of my chest, my pulse quickened even worse than it had been, my stomach turns and I feel everything come up, and I projectile puke like in the Exorcist movie, and it's going everywhere! It doesn't stop after one puke, oh no! We're talking 3 projectile pukes! I can't even move closer to the restroom. I just fall to the floor, completely weak & out of control, all cold and sweaty, now just puking and puking. It's everywhere! Then when I stop, I immediately feel better as far as the nausea and all those other side effects. Lol, but now I have this huge mess! And still no poop! Plus, I'm like great, after all that, now the MC ain't even gonna work because I puked it all up! Boy, was I wrong! I got cleaned up and went to bed! Then about 2:04 am, I awaken with the urge to fart. I run to the potty! And oh yeah! It was like I pooped out the Titanic or something! Once I was done pooping out the poop the size of a killer whale, I wiped, washed my hands, and was gonna turn off the lights and shut the door. Then I was like, ohhhh boy! I had to run back to the potty, lol, for an encore performance! I puked it all up, lol, I thought noway this isn't gonna work now! But it did! Dude, I feel like I pooped so much, my legs hurt from flexing them while trying to push. Lol, my calves and ankles feel like they are about to fall off, and my butt feels raw. Lol. It's now 6:56 am, and I haven't had to poop again, thank goodness. I don't know where it would come from. Lol. All stool was intact, no diarrhea so far!"

Magnesium citrate for Constipation "I highly recommend this product. I have been constipated for several weeks now, and my doctor recommended 2 days before colonoscopy (in addition to prescription prep). I chose grape-flavored CVS brand. I refrigerated it the night before and took it at 6:45 pm the next evening. It is very sour but carbonated, so it was doable. A family member suggested that I eat at the same time to cut down on nausea, which really helped. At first, I felt like my stomach was going to explode because I drank the 10 oz bottle followed by 16 oz of water. Then there was a lot of stomach bubbling. I finally was comfortable enough to lie down and eventually fell asleep, to be then awakened by this urge to pass gas at 12:40 am. Don't do it!!! Find a toilet fast! It works!"

For Constipation "As I was reading reviews wondering when this kicks in, it happened. Took 10 oz in the afternoon and again in the evening for colonoscopy prep, didn't drink enough water, and only made 1 movement. Thought '30 min to 6 hours til it works? Did I do it wrong? It's been almost 12.' Yes, I did. I didn't drink enough water afterwards. Drink lots of water! I woke up at 2 am and didn't trust a fart. Tummy gurgling, sitting down, browsing the net, and boom. You'll pee out your butt with this, no joke. Give it time and it'll take anywhere from 30 mins to 6 hours to kick in, possibly 12 if you're me and didn't drink water after. Got it for 97 cents in cherry, grape, and lemon flavor. They all taste like super sour candy and it helps to take with Gatorade."

For Constipation "Okay. So I felt discouraged about this because I've been reading reviews where everyone had a successful bowel movement so quickly. I have been backed up for 3 weeks. I feel like it's from stress and life changes. My routine was different. I have tried 2 enemas and I was only able to get small rabbit-sized poop. I actually couldn't take it anymore and went to the ER. Wish I didn't because they didn't do anything but tell me to drink the magnesium citrate and do another enema. The enema wasn't too successful. I tried magnesium citrate at 8 a.m. Chugged the whole thing. Drank water. I waited and nothing. I felt so disappointed and felt miserable that I was going to have this stuck feeling with no result! 16 hours later came. Gurgling and pain. I went to the bathroom and released two massive pieces I've ever pushed out ever. Sorry, TMI, but I guess that's what's been backed up!!! So if you think it's not working, I guess I'd wait 24 hours. I feel so relieved now!"

Magnesium citrate for Constipation "I have been stressed for many months. My nutrition and water intake have changed, and my stomach has been uncomfortable for over a week. I chilled my 10 oz bottle for 30 minutes and had dinner. I drank it around 7:30 and thought I was ready by 8. False alarm, but by 9:45, it began to work. The drawback is, almost a day later, I'm being cleansed. I used the lemon flavor. To make the taste more bearable, chill it and use a mint afterward. Make sure to drink 8 oz of water as the instructions state."

For Constipation "I have chronic constipation, and this is the only laxative that works for me. I had to go to the ER for the second time in a few years due to not having a good BM in a few weeks. They recommended the magnesium citrate again for the second time around, and if you are chronically constipated, IT WILL TAKE A WHILE, so make sure you have the next couple of days off. This last time, I took a whole bottle (10 fl oz) around 8 pm at night. I woke up the next morning feeling nothing, so I took another half bottle (5 fl oz), and then within the next 2 or 3 hours, the rumbling and flooding started and lasted the whole day. Make sure you have baby wipes so your bottom doesn’t go too raw, and apply ointment before it all starts and during the event as well. It is 1 am Saturday morning, and I am having bloating, nausea, and a terrible stomach ache. I knew I was going to have diarrhea, but I didn’t know how gross I would feel the next night, and I’m back to going to the bathroom. VERY effective for people like me, but nasty side effects."

For Constipation "So, the taste (doctor recommended the lemon flavor, but I'm feeling like I should have gone with cherry instead) is similar to that of rancid vinegar. As soon as I chugged the 10 oz bottle, I began feeling really sick to my stomach. I even vomited. After about 30 minutes to an hour, I decided I had enough. My stomach started churning, and before I knew it, I was running to the bathroom. I stayed glued to the toilet seat for a good hour. Basically rinse and repeat that for the duration of 5 or 6 hours. The remainder of the medicine just leaves my stomach feeling terrible and noisy. Good medicine, bad side effects."

For Constipation "I've been having terrible stomach issues lately. I tried two kinds of Dulcolax, tried staying hydrated, tried everything, but nothing worked. Finally, today I got a bottle of the lemon-lime magnesium citrate, 10 fl oz, and downed the whole bottle. I've been leashed to my throne on and off for about 8 hours now, so... Yeah, it works."

For Constipation "I had been so horribly backed up that I could feel the skin on my stomach stretching. I tried taking herbal colon cleanse pills in hopes that it would help, but after 4 days of zero bowel movements, I decided to turn to Magnesium Citrate. I took 10 oz first thing in the morning on an empty stomach, followed by a liter of water. 30 minutes later, it kicked in. For about an hour and a half, I also had nausea and stomach cramps. Once things started moving more, it went away. Like another reviewer said, this will make you pee out of your butt. If you are looking to be cleaned out and immediate constipation relief, I highly recommend this product."

For Constipation "So I haven't had a BM in 5 days. Being a nurse, I went through the usual motions of trying to accomplish one, but to no avail. I started getting frustrated and decided to step my game up. I used stool softeners, suppositories, milk of mag....and nothing. I was dreading the thought of a visit to my doc, so I tried Mag Citrate. This is generally what I give a patient for bowel prep or as a last resort for severe constipation. I picked up some grape-flavored Mag Citrate from CVS last night. I went conservative and consumed 5 oz of the 10 oz bottle. By 8:00 am this morning....nothing. But I was starting to experience some gurgling in my bowels. I commenced with drinking 12 oz of coffee and another 8 oz of water. Bingo, we have action."

For Constipation "Well, I promise if you are reading these reviews they are all true! I have been on the toilet for the last hour, stuff just streaming out of me. I have been incredibly constipated for the last few weeks, and I remember my mom always used mag citrate whenever she was really backed up, and oh lord do I know why. I don't think there is a single bit of poop left in me, but it just keeps coming out. The only downside is that my bottom is kind of feeling a bit hot, and that my stomach won't stop making these god-awful noises. My boyfriend was like, 'Oh my god, what's wrong with you?' hahaha. But as everyone else has said, be prepared to be on the toilet for a while."

For Constipation "Drank an entire bottle of lemon magnesium citrate around 10 AM for bad constipation. About an hour later, small rabbit poop, some gurgling, sat home afraid to leave the house all day due to reading all of these reviews. By 3 pm, got the courage to leave, run around, and go to the gym. Home around 7 pm - ate dinner, and within 20 minutes, peeing out of my butt and feel 15 lbs lighter."

For Constipation "First, I have IBS/IBSD. So a bowel motion (BM) every day is normal for me and anticipated. I haven't had my normal BM for 3 or 4 days. Bloated, distended stomach, and yesterday, cramps. Something had to be done as I was miserable. Magnesium sulfate did nothing to help the problem. A coworker got me a gift of MC. Told me if that doesn't make me poop, then I need to go to the ER. I drank half at 7:30 pm. The cherry is insanely sweet and tart...disgusting. No relief by 8 pm, but lots of rumbling in my stomach while a little scared to leave the toilet. So I downed the other half, drank some water, and went to bed by 8:30 pm. At 3:20 am, my dog insists on me getting up. Did I mess myself? No, he's just being a crying land seal (pittie) and won't stop until I get up. My stomach felt a little bubbly, so I went to use the bathroom. It's now 4 am, and I haven't stopped peeing out of my butt (not out of the norm for my IBS/IBSD). It's definitely working, and I'm glad my coworker got me this!"

For Constipation "Though the taste is horrid and it does supply some side effects (stomach gurgling, mild cramping), this stuff WORKS. Though the bottle says half an hour to 6 hours, give it a full 24 hours before you discredit it, for me, it took around 10 hours. It may not feel like it's going to work, but the urge will come fairly abruptly. You'll need a day off of work, a lot of toilet paper, water, and your phone or some reading material at the ready!"

For Constipation "I've been trying everything to go to the bathroom to poop. I take a lot of medications that cause constipation, including opiates, daily. I suffer from chronic constipation. I took this stuff at 6:30 pm. I went a little about an hour after I took it, woke up the next morning at 7:30, and had a few liquid poops, but nothing major like I expected. I have a stomachache. I don't think it worked for me."

For Constipation "It took me 14 hours. Hurt quite a bit as a large lump was stuck in the rectum. Once this piece came out, everything was cleared. In my opinion, magnesium citrate made the price a little bit soft and helped pass, but there was excruciating pain while the first pass, and stomach cramps were very bad. I also took Doculax, so I do not know what caused the cramps."

For Constipation "Having opiate-induced constipation and on methadone, bowel movements are a commodity and a gift. On my fourth day of no pooping, I began to panic and read about MC. Went to the pharmacy, picked up the lemon-lime flavor brand of Citrodan. I actually drank half the bottle on the way home, and within 45 minutes, I was on the toilet excreting the most foul-smelling bowel movement I have ever had. The next few hours were a bit uncomfortable: gas, gurgling, running to the toilet, and some cramping. This stuff does what it is supposed to do with fervor and dedication. Be prepared and stay in. It's best to do it in the morning so you have all day to expel. Drink lots of water throughout the day and wash. It does smell bad coming out."

I took this at 6:45 a.m. and had terrible stomach cramps and felt nausea. It really did not kick in until about 12 p.m. Now it has been 11 hours. I'm still going, and my stomach sides and back hurt, but I feel relieved. Drink plenty of water and don't forget to have wipes and ointment ready before you start."

For Constipation "I drank a 10 mL bottle of the lemon-lime flavor at about 7:00 pm and had to spread it out because it made me nauseous, and I couldn't handle the taste. So I finished it at about 8:15 pm, and I had been sipping about 15-20 oz of water along with it. This has been a painful experience so far (it's currently 12:15 am). I have had intense cramping in my lower abdomen that makes me feel like I constantly have to poop. But I really have not been able to go a whole lot (when I do, it's pure liquid as many other reviews said), but it also made my stomach so upset and caused considerable nausea. So in between bouts of diarrhea, I was dry heaving/retching over the toilet, but no vomit so far. The pain is nearly unbearable, and I just wish it would stop."

For Constipation "Well, I read many reviews here before I took the MC. Lots made me laugh, but y'all gave me a concern. As we were traveling, I did not want to be in an explosive situation, however, I was pretty desperate for relief. So, at 7 pm, I drank 1/3 of a bottle of CVS lemon. And it is NASTY: syrupy, tart, and difficult to get down. I drank about 10 ounces of water and waited. A few belly rumbles, but nothing. So, at 9 pm, I took a bit more-drank down to the halfway point. And more water. At 10 pm, the urge hit, and I managed to pass 2 extremely painful, huge, bulky stools. What I think happened is the smaller amount I drank started to work higher up in my colon but did not get a chance to penetrate things further down. Not pleasant, but it got the job done. The upside is I was able to travel the next day without incident. 1/2 a bottle worked for me with lots of water-thanks. Try to be patient and take as little of this as possible. I cannot imagine how people survive taking multiple bottles!"
