For Constipation "I haven’t had a bowel motion in days. I have been so backed up and anything I try to pass is 100% rock hard, terrorizing pellets. I took it last night at around 9ish, drank tons of water, and have been straining all night. Wow, help me, I thought I was going to push out this baby instead of the rock in my booty. Finally, at 5:30 am, I felt *it*. I went to the toilet and braced the walls for what came next. One, two, three painful pellets, then WHAM like Hiroshima - I was cleared of this butt block."

For Constipation "So, a bit about me. I am a regular guy - regular build, height, size. Aged 61 and a Leo (not that this makes a difference). When I say I'm a regular guy, I mean that in the last 60 odd years I have been as regular as clockwork in the BM (Bowel Movement) department. That was until last Saturday morning. WARNING: GRAPHIC DETAILS FOLLOW: (Written in layman's terms.) Day 1: Saturday, I awoke, went to the loo, nothing happened! I sat there needing a wee, and if you are like me, during or shortly after I wee, I poo. Not today! Got up off the loo and went about my day. Several times though, the day I went and sat on the loo and tried to pee, with just a trickle for my efforts. I felt that I really needed to poo. As the day went on, I felt almost as if each bum cheek was solid - I mean rock hard. (That's not good) I was thinking to myself. Still unable to poo and pushing on each bum cheek to try and move stuff about a bit in the hope that I might be able to squeeze a bit out. NOPE! Went to bed. Day 2: Sunday, I awoke in the morning really needing a wee and a poo. Still rock hard bum cheeks but now liquid poo was dripping/running out of my bum. This persisted throughout the day every time I sat on the loo. I spent four hours sitting there trying desperately to go, the pain was so bad, I was literally screaming in pain. The pain was situated mostly around my perineum. I would describe the pain as having an elephant standing with its back legs on your dick and its front legs bouncing on your bladder. OOOOOOOOOOOOOOOOOuch! This continued all day. I tried two tablespoons of olive oil mixed with fresh lemon juice and loads of water. NOTHING! Day 3: Monday, I woke up, went to the loo, worked on massaging each bum cheek, had a small motion. When I say small, I mean the size of a pea. I was, however, able to pee (oops, I mean pee), still rock hard impacted bum dripping with runny poo. I worked on each bum cheek, rubbing and massaging as I sat on the loo for what seemed like most of the day, gradually I was able to work most of it out as it became slightly softer. Day 4: Tuesday, woke up still unable to poo but weeing with ease when I needed to. Bum cheeks felt normal (bit saggy as I'm getting older, I used to be such a fit, tasty kind of guy with a great arse). Today I am getting worried as I have never had anything like this happen to me. I have always been fit and active, never taking any time off. I go on the internet and find this forum. After looking at loads of others, I am not anti-meds but only use them as a last resort if all else seems to fail. (I am a fourth-degree Reiki Master Practitioner and a black belt so fairly fit most of life). I remember my mother used Milk of Magnesia, so after reading the comments here, I went and got some and took 15ml at 17:00. I did read the instructions but decided to take some, my thinking was before I go to bed, wrong! Nothing happened, so at 23:00, I took another 10ml and went to bed. Day 5: Wednesday, I awoke feeling as I had done for the last 4 days, still wanting a poo, desperately wanting a poo and pissed off that the MOM had not worked yet. I sat on the loo, had pee and nothing! Went outside to inflate my wife's car tire, which has a very slow puncture, so got the compressor out, attached it to the valve, and as I bent over, I thought to myself I think I need to go to the loo. So slowly walked back indoors (no urgency at all), sat on the loo, and my bum exploded in an instant with such force that it truly stunned me. OMG! No pain, no cramp, no nothing; almost no sensation at all, except the most amazing feeling of not being full of poo (which I have been accused of on more than one occasion) (wrongly, I have to say, being a Leo, apart from the last 5 poo-filled days). Been twice again since this morning, it's now 14:15 and having just finished this, felt I had to say it's fanbloodytastic. Be warned, it can happen very, very quickly and almost violently when it does, in my case, without any warning and I'm happy to say without any pain or cramping at all, just lots and lots of noise and splashing and shouts from me (not of pain but of great relief. That must be the understatement of the year). 10/10 for Milk of Magnesia. Once again, Mr. Regular!"

For Constipation "Pregnant lady here. I had been suffering from extreme constipation; no bowel movements for well over a week. I could feel the pressure in my pelvic area, but couldn't get more than a few small pebbles at a time, and I had to labor for them. I drink plenty of water and eat healthy. No known medical issues aside from pregnancy, but this was getting ridiculous! My OB's office suggested MOM. I absolutely gagged drinking it, but 4 hours later... I was in so much pain I didn't think it was going to work the way intended. Then finally... I got up to the bathroom, and that massive blockage is gone, and then some! Other things I'd tried would leave my butt on fire or feeling like it was going to rip in places! This stuff works on all levels! I don't know if I'm going to be getting a lot of sleep tonight, but my stomach is no longer hard, I'm no longer in pain, and my rectum is finally empty! It definitely feels like the medicine isn't finished with me yet, but I'm so relieved! This stuff works!"

For Constipation "Thank you! I just finally passed two very large bowel movements. Aaaaaaah.... I took the maximum 60 ml at noon and laid down to take a nap to forget about all the pain I was in. Then at roughly 3 pm, my eyes popped wide open and I made a beeline for the poor toilet. MoM always does the trick. Phew!! Probably the only medicine on the market that does what it says on the tin. Aah. Shew... You better stock up on this stuff before the liberals take it off the market for working too well."

For Constipation "This stuff is the real deal. It really clears you out. I had my gallbladder removed and was on pain meds, so I was unable to 'go' for at least 5 days. I panicked because normally I poop 6-7 times a day. So I called the nurse scared. She suggested milk of magnesia. The bottle called for 2 tablespoons, but I felt so bound and plugged up that I chugged 3 tablespoons. And it began. 20 minutes after I drank it, it was like an explosion of chowder every 10 minutes. I'm glad it worked, no cramps, no pain, just extreme anal gushing, and this happened every 10 minutes, making it inconvenient and annoying, but hey, it had to be done. I got the berry-flavored one, and it was relatively tasty."

For Constipation "I had been constipated for a week, so I decided to take some cherry MOM. I took the recommended adult dosage at 12 PM, and by 1 PM, I felt an awful pain in my stomach and rear end. I jumped up and ran to the bathroom. I was so relieved and thought it was over, but NO. I've had diarrhea since. It's coming out explosively like water. Now my bum is sore. Yes, this works, but be prepared to be near a toilet!!!!"

For Constipation "I had jaw surgery 2 weeks ago, and I have to be on a liquid diet for maybe less than 6 weeks, but can also have very soft foods. After a week and a half, I started eating scrambled eggs, and then a couple of days later, I had to go poop and COULD NOT come out. It was painful and to the point I was crying. Then I was researching on what is the most effective out there... Magnesium Citrate. I went to Walgreens with my dad, and he said when he was a child, this was the BEST solution that helped him out with his constipation. When I bought the Wild Cherry flavor of MOM Phillips, I took it right away. It immediately helped out the cramps because it was extremely painful. Then I went to take a long nap, and then 5 hours later, IT CAME OUT LIKE A DREAM. Try it, please!"

For Constipation "Best laxative out there! I have chronic constipation due to psych meds. I've tried every laxative out there and have a very healthy, plant-based diet, etc., but nothing has helped. Milk of Magnesia is the only effective remedy I've found. Best to take it on an empty stomach-it doesn't seem to work if you're full of food-and drink lots of water. Within 2 hours of taking 4 tbsp, I had 2 bowel movements. No cramps or bloating or pain or diarrhea. This stuff works great."

For Constipation "I've never had problems with my bowel movements. However, I just had to have surgery and was taking a narcotic - mostly to sleep at night. I had a small bowel movement the third night home, but then felt horribly constipated. It was almost worse than the operation. It was painful, uncomfortable in my belly, and bloating. I took olive oil, ate fruit, did all the things to get my body moving. I walked around for hours. Still, nothing. Finally, my mother came over with the Phillips Milk of Magnesia, and I took the largest amount. Nothing right away. I became frustrated and took another two teaspoons about three hours into waiting. Exactly six hours after I took the first dose, my system finally kicked in - BIG TIME. It was really painful, but relief."

For Constipation "I suffered from diverticulitis 15 years ago. Had to have part of my sigmoid colon removed after it perforated, almost died from the infection. Things went well for 7 years, until I had to have surgery again because of blockage due to stomach adhesions, which they say is typical after that kind of surgery. In each of these incidents, I was unable to poop, and my stomach grew to the size of 2 watermelons! It was so painful. Well, it happened again! I couldn't pass anything but a few hard marbles for 2 weeks! The pain and gas were horrible! I tried everything, Senokot, prunes, etc. I was getting really scared that what was left of my colon would explode and I would die! I took a dose of MOM, and voila, it worked! Be near a toilet for several hours, though!"

For Constipation "Taking painkillers for shingles, I was constantly bloated and in pain with constipation. In fact, my stools were impacted. I tried several laxatives to no avail. Then I remembered as a child, Mom giving us Milk of Magnesia. So I got a bottle from the chemist. I did as the instructions said: 15 mL. It worked a treat."

For Constipation "I changed my diet about 6 months ago and just recently (the last month or so) have been experiencing constipation. Before this, it had been very few and far between. Roughly every 3-4 days is when I would have a BM, not comfortable at all. I finally caved after having horrible bloating and pain at work today. I went to the drug store and picked up a bottle of MOM. I took 2 tbsp about 7 pm. I didn't have any discomfort or gas, but I couldn't sleep very well either. Finally, about 1 am, the blockage is gone, and I'm so much more comfortable. I didn't experience any cramping, and the beginning was still somewhat difficult to pass, it was soft but very bulky still. I don't feel any further urges to go to the toilet, but it's only been 20 minutes."

For Constipation "Took at 9 a.m., hoping to move bowels the same day, after days of horrible constipation and bloating. MoM claims it works within 6 hours, but nothing happened. I took another dose at bedtime, still without any movement. The following morning, I have awful diarrhea. It's so bad it gave me an anal fissure, and I've been taking Imodium and putting on lidocaine to ease the pain. Ridiculous to go from one extreme to the other. Yes, I should not have taken a second dose, but thought it would be fine since it did not work at all after 14 hours, and supposedly, you can take this daily. I thought this would just quicken transit time, but no, it stayed in my gut, mushed everything to liquid, and gave me the worst diarrhea ever. Never taking again!"

For Constipation "I am rarely constipated and am not sure what happened to cause it this time. I eat a good diet, drink plenty of fluids, walk, and take supplements, including magnesium, twice a day. My doctor recommended a stool softener, and it did not help. I tried a Fleet, which allowed some stool to come out but did not unblock. My doctor's office recommended the MOM, but I resisted because I was already taking magnesium supplements. I finally tried it. Nothing after 6 hours, so I took another dose but did not exceed the maximum. First attempt, nothing but bleeding from straining, and shortly later, the second attempt expelled a small amount from stool and again. Went to bed, and in the morning, I had an urge and went again, and my butt was in pain but some relief. Had my coffee, and minutes later ran to the bathroom and exploded. Not diarrhea, but the rest of what needed to come out. Not as bad on my butt either. Made a believer of me. Would advise to try 30ml first and repeat if it doesn’t work in 6 hours."

For Constipation "I took the max dose of it after breakfast for the first time for chronic constipation. I didn't have a BM after 7 hours and just had horrible heartburn, stomachache, nausea, bloating, and vomiting. It was basically a lot of pain, and I was so sad that I took this in the first place because the pain was worse than not pooping for 2 weeks! I got a BM the next morning, and it was completely watery diarrhea, and it was the worst pain ever. I told my doctor that this is just painful, but he told me I have to take this because I already tried everything, nothing worked, so MOM was the last choice. I already done a test, and it was all normal. Anyway, it was the worst pain ever, and I would NOT recommend this!!!"
