“I used the Philip's gentle over night relief version of this (30ml seperate doses), It works but it took about 15 hrs to produce results rather than the 30 mins to 6 hours they say on the label. One major thing I'm not a fan of is how wet it'll start getting down below within the first hour of taking it. Also make sure you keep a drink and maybe food with you as this can dehydrate you pretty good in the process.”

“Only take this for constipation if you need to poop so bad that you won’t mind sleeping on your bathroom floor. 10 hours of 20 min intervals of liquid brown water. Started at 11am with the minimal 30 mL, (I did not wait to do overnight because I had nothing but time seeing as I am out from work because of a surgery). First dosage gave me nothing but some angry stomach noises even with drinking plenty of water. Took a second dose, same day of 30 mL (still not exceeding the max of 60 mL) around 10:30 pm, nearly 12 hours later and that’s when the trauma happened. Relief? Yes. in the way I wanted it to be? Absolutely not. I am exhausted with aching butt hole, thankful for baby wipes.”

“I am not the type to write a review, I never have. But, I just needed to say how well this worked for me. I have been constipated for 4 days now, I took 4 tablespoons of MOM and drank water. Approximately an hour later I chugged more water and it hit me and cleared me out. This works wonders.”

“I eat very healthy, plenty of fiber, drink lots of water and get plenty of exercise, but could’t poop for three days. I was only able to force out a small baby carrot sized BM once a day when I normally produce a lot more once a day. I continued to eat like normal expecting the big one to come, but it never happened. On day three, after I ate lunch, I felt so bloated and uncomfortable which was not normal. I also had such atrocious smelling farts that the government could have used the same smell as a biological weapon. At this point I started getting concerned. Went to the store and bought some M.O.M. Took the full dose at 9:00 pm. An hour later, I felt a slight urge to go. Sat on the toilet and it happened. The flood gates opened and the butt cork was now gone. It flowed out of my bottom like a faucet and it just kept on coming. Three flushes later I was finally able get up off of the toilet. Worked well for me. 10/10.”

“I get constipated almost every month, I have used MOM every since I remembered thats what my mother used to give me as a kid when I got blocked up, I take about two tea spoons at night and the next morning everything gets flushed out rather rapidly. No pain, just great relief.”

“I figured I’d share in case others find themselves in the same predicament with constipation. I am on stool softeners and fiber supplements which normally keep me going but I went 4 days without a significant bowel movement and it was getting uncomfortable. I took the max dosage before bed and didn’t have a bowel movement the next day other than small hard stools. However, the day after literally everything came out. Just a heads up that it can take 1-2 days to work but it works well.”

“I am 19 years old and have battled extreme constipation since birth. Usually I can have a BM from drinking coffee in the morning at home, but it is a hit or miss system. Sometimes it doesn't work and my discomfort grows. I have tried suppositories, enemas, stool softeners, prunes, Miralax, and the like. These things have worked but often are quite painful and only a temporary fix. I took 30 mL (2 tablespoons) of MoM at 8:40am this morning. I did not take it before bedtime as instructed because I was not interested in being up all night as some reviews forewarned. Along with a cup of coffee at noon, I was able to have a BM at 12:40pm, so almost exactly 4 hours after I took the MoM. It definitely softened my stool and made it easier to pass. It did not give me diarrhea nor watery stool. Happy things are moving again. Also remember to drink water as this product pulls water from near tissue.”

“I am a recovering addict taking methadone daily, this opiate (like 99%) of opioids it constipates me bad. Pooping once or twice a week. Never easy, usually tiny rock hard pellets. Tried a lot of things with nothing else worked so I tried MoM. downing two large "gulps" figuring it'd never work at doses lower than a bit over max- opps I was wrong! An hour later I'm hunched over catching my breath after the most explosive, frankly nasty yet super fulfilling movement... point? This stuff doesn't mess around!”

“If you take the recommended dose it will work gently and effectively in about 6 hours. I use it whenever needed, pleasant taste and no cramps. I have found this to be the best laxative. A word of caution, don't take much more than directed; the first time I ever used this I wasn't wearing my glasses and didn't notice the markings on the side of the dosage cup. I mistakenly thought it said 4 cups rather than 4 tablespoons on the label. That meant I took 4 times more than recommended. That wasn't all- I also didn't notice it was the concentrated stuff-twice as strong. therefore it amounted to 8 times the regular dose. It started working 2 hours later and I spent most of the day and the next day in the bathroom.”

“First time user; took the full dose (4tbs) because I'd been constipated for a week and felt very uncomfortable. I did not drink a full cup of water with it, thank goodness. You'll see why later. First BM came about an hour later (not much) and second one about 3 hrs later (bit more). I was disappointed because I thought that was it but felt there was more. Around hour 5 I had a slight urge to go... so I sat down and whoa!!!! Everything just fell out. Seriously, no effort and absolutely no pain. There was a LOT of water, despite the fact that I didn't take the med with recommended full cup of water. I feel light as a feather now. MOM is very good stuff, I'll definitely use again and highly recommend!”

“I was constipated for 1 week (the usual) so I took the maximum amount. Oh and I took the “Original flavor” because thats what was in my house. And it taste like dead fish and baby diapers, so when I take a cap full I throw a starburst in my mouth along with water hehe. So on Tuesday I took a dose because my tummy was severely bloated. But only a lil came out. Then on Thursday I had a huge blow out (it was amazing). No cramps but I was weak, and had some nausea and felt faintish but it was bearable. I just ate on time and drank lots of fluid. Then on Friday I'm starting to feel a lil better. Still weak and slight nausea. And occasional bowel movements. I took lipton to make my #2 just a lil harder. But I love MOM. Used it 3times so far and it always works.”

“This stuff works! Haven’t had a bowel motion for 4 days now and within the 4 days using miralax and stool softeners and hot water drinking... but nothing. Finally went to the doctor and they told me to try milk of magnesia so I did. Within 2 hours I finally had a bowel movement and looks to me like I cleaned out my stomach. I took the 60ml dose from the bottle instructions but now for a week I’ll take half again soon each day so I can continue my bowel movements.”

Me · Taken for less than 1 month September 2, 2019

“Dr. took me off of a medication that caused constipation and I still couldn’t go for a month. I was getting so weak and I didn’t know what to do. I prayed about it and milk of magnesia was what I got. Yes it worked! I feel so much better. I think medication gets stopped up in the intestine and stays with you until you get it out. I’m so happy about that. I took 4 tablespoons and it worked within four hours but I have diarrhea and not sure if I’m supposed to have stools yet. I will wait and see. This was my first time for using it in a very long time. Hopefully I’m no longer stopped up and will go regularly now but if I need to use it again I will.”

“Y'all.... Was having some discomfort from constipation and bloating. My stomach just generally felt horrible. Wanted quick relief so I took 4 tbs of MoM. Yes, you read that right, FOUR TABLESPOONS! I have been off and on the toilet for the last hour and realise now I took too much! Will definitely use again in a much lower dosage.”

MarissaR8897 · Taken for less than 1 month July 8, 2017

“This stuff is a freaking miracle worker. I have chronic constipation and can go weeks with no BMs thanks to my doctor prescribed diet. Now if I were to tell you nothing else worked, I'd be lying. Everything worked. However, this is the only product I've used that didn't leave me writhing in pain. Magnesium citrate, all stimulant laxatives, and even natural remedies gave me such awful cramps they'd double me over and sometimes for days. Even saline laxatives made me queasy and ill feeling for several hours post BM. I thought I was out of options until I came across this at the Dollar Tree. No cramps, no discomfort, doesn't keep me up at night, and a BM like clockwork 5-6 hours after consuming. It completely empties me out!!!”

Pregnant and poopless · Taken for less than 1 month July 17, 2017

“I'm 8 weeks pregnant and have been having trouble with constipation. I also have problems with nausea and vomiting so I know my intake of food and water hasn't been the best. Today I felt the urge to have a bowel movement and was really excited to do so, as that hasn't been happening for a couple weeks and I had to take an enema about 3 days ago. I tried to make a BM and nothing but a pellet came out and I was left with stool in my rectum which caused a good deal of pain and discomfort. I literally could not sit down. I managed to make it down the street to CVS for MoM (cvs brand). I took about 45 ml + water at first and then about 20 min later I took the additional 15 ml + water. 6.5 very painful hours later baseballs come out. Relief!”

After a few hours in pain I went to the market and purchased MOM.....within one hour of taking it with a glass of water it worked.....the results were AMAZING!!! everything was gone and I felt very clean!”

“Milk of Magnesia is the only effective laxative I ever took that didn’t irritate my stomach lining or cause prolonged diarrhea (and I’ve taken them all now, for opiate constipation). Eg. last time, I took 60 ml MOM after 5 days with no BM and nothing happened, so I took magnesium citrate, which gave me horrible cramps & diarrhea lasting 3 days & stomach felt it had been strip mined for a week. Couldn’t drink juice or soda after mag citrate, without feeling like my stomach was a pit of fire for hours. THIS time I took MOM on the 2nd day with no BM & a feeling of gassy fullness. In 2 hrs, had a well-formed stool & went to bed. In the AM, passed a lot more, but normal, not like it had been marinating in a vat of acid. Tiny amount of watery stool at the end but that was it. No pain, cramps, diarrhea, irritation, or dehydration the next day. Went to work. Good thing I took it before it got too bad this time. I will always keep some on hand.”

“I am 23 years old and have suffered from stomach issues and constipation most of my life. In the past several years, I have struggled with IBS-C and have really bad constipation during my flares. I have tried just about everything to relieve my constipation specifically prunes, miralax, Metamucil, extra fruits/veggies, and lots of water. Nothing seemed to help and I was getting frustrated! Finally I was at the store buying some Gas-X, when I came across Milk of Magnesia and called my mom to see what she thought. I ended up buying it and took the 2 tablespoon dose at night with an 8oz glass of water and went to bed. I did feel the gas and my stomach rumbled all night but no action until I got up and ate. It definitely cleared me out!!”

“for a couple days I wasn't eating very well and I noticed I wasn't using the restroom regularly. I went and got fruit and stuff with high fiber and I was still stopped up except for occasional little stools. After not being able to go fully for a couple days I started getting very bad abdominal cramps and I started vomiting. I went to CVS and bought milk of magnesia took three tablespoons of it and 30 minutes later I got diarrhea. I feel better my stomach doesn't hurt anymore and I'm not vomiting. I would recommend this to anyone with constipation problems but be prepared for multiple toilet trips”

“After giving birth, lay up in a hospital bed and taking all kinds of medicines. Milk of Magnesia is the best way to get the well needed relief. For me, it doesn't cause any of that rumbling you get with laxatives. Thanks.”

“I suffer from constipation due to taking opiates (Subutex to be exact) and lately I’ve been having a HARD time poopin’. I took this while pregnant and after I gave birth. Worked as intended. I took the whole cap full a couple days ago and I’m still feeling the effects two days later but its tapering off. I tried a stimulant laxi, magnesium, etc. This was pretty much same-day effective for me. Within hours to be exact. I would definitely recommend being home for the whole day or close to a toilet....”

“Took MOM (milk of magnesia ) yesterday afternoon around 3:40pm to be exact. It did not start working until almost 7 hours later and it’s still working after 12 hours later. Started out as very watery stools, then it hit like crazy. I hope I never have use this again. Definitely works thats for sure. Just don’t go far from the bathroom and drink water to keep from being dehydrated”

“I have motility issues (i.e., idiopathic constipation) and Milk of Magnesia works, but causes severe bloating, for me. For anyone with this issue, Dulcolax is enterically-coated, so no bloating. But, the urge to 'go' comes on very, very suddenly.”
