Magnesium sulfate / potassium sulfate / sodium sulfate for Bowel Preparation "The smell is deceiving, it smells sweet and fruity, NOT!! It is just one of the nastiest things I've ever put in my mouth. Although I did chase it with Gatorade, which seemed to wash away Suprep aftertaste. The diarrhea wasn't anything I haven't had before. This is my second colonoscopy. Was more worried about the prep than the procedure. The lemon-lime stuff I drank the first time was way better tasting. If you have a weak stomach, ask for something else."

Magnesium sulfate / potassium sulfate / sodium sulfate for Bowel Preparation "1st dose went down within 25 minutes. Lots of juice in between sips. Taste is terrible! Shooting clear poop by 2nd poop. 2nd dose only able to consume 1/2 due to nausea. Everyone mentions using wipes since your bum is sore from going so much. Frankly, I didn’t go much... the very 1st poop was like razor-sharp shrapnel cutting my bum. I begged my doctor for an alternative, she said no. I suffer from IBS-D... lots of diarrhea. I didn’t feel I needed the prep at all. And frankly, I wasn’t far off. I only consumed about 4 oz on 2nd dose. Doctor said I was very clean, which further angered me and proved someone should have listened. The whole experience was humiliating, intrusive, and difficult."

Magnesium sulfate / potassium sulfate / sodium sulfate for Bowel Preparation "Prep was okay. After the colonoscopy and now 5 days later, I am still having diarrhea, stomach distended, grumbling, chills, loss of appetite, and major dehydration. I had to go to the ER for a CT scan and hydration. No bowel perforation - thank goodness. (Had one 10 years ago). The adverse effects are awful, and the doctors don’t know what to do for me. Anybody have this?"

Magnesium sulfate / potassium sulfate / sodium sulfate for Bowel Preparation "Took the first dose of Suprep at 5 pm and could not make it through the 16 oz before vomit, stomach pains. Drank as much water down as I could, which was about 16 1/4 oz. About 45 min later, projectile vomited, called the doctor’s office, they said to keep going with the second dose in the morning. Two hours later, started passing diarrhea, had four short visits to the restroom. Fell asleep, minor nauseous, woke up at 1 am for the bathroom and drank some water, nausea was pretty much gone. At 6 am, started the second dose. At this point, I was still passing regular diarrhea. I could only get down half the dose before stomach pains, so I stopped and switched to water. Did not want to throw up my second dose. Thirty to forty min later, I was good enough to try again, but only got about three gulps. Drank the rest of the 32 oz of water. By 9:20 am, was running clear/yellow with minimal particles. I am not a fan of this prep or process, but so thankful that I made it through."

Magnesium sulfate / potassium sulfate / sodium sulfate for Bowel Preparation "This medicine has a chalky grape flavor. It wasn't bad at first, but got to the point I had a lot of trouble drinking all of it and not puking it up. It comes with 2 bottles you mix with water. After you drink one bottle, you have to drink 16 oz of water and then drink the 2nd bottle, and then drink another 16 oz of water. I had a lot of trouble not puking after the first round. I don't know if I drank all that stuff too quickly or what because there were no instructions on how to drink the water time-wise. I couldn't drink all the water on the 2nd round. I got really sick trying not to vomit and shaking. The kit gives you diarrhea in about 30 mins after drinking. I took it at 6 pm and still had diarrhea the next morning. It subsided that afternoon. Little cramps."

For Bowel Preparation "A lot of people are not bothered by this, but I sure was. Chilled it, and used a straw, and sucked on a lemon. Managed to get the first dose down, although it took longer. The second dose, at 3 a.m., did me in. I could only manage about 70% of it. I got nauseated and didn't want to throw up what I had already gotten down, plus I ran out of time to drink the water after. I ended up failing my colonoscopy-what a waste of everyone's time. Plus, I was still having episodes of diarrhea and was so afraid I'd poop my pants at the endoscopy center. Everyone there was great, but the Suprep was a nasty experience. I will never do it again. If you have a hard time drinking or gulping fluid, and are usually just a sipper, beware."

Magnesium sulfate / potassium sulfate / sodium sulfate for Bowel Preparation "Took Suprep prep for colonoscopy on 2/3/2020. I’ve had three previous colonoscopies. All three previous, the prep was only the night before. I drank the second half of Suprep at 4 am, arrived at the doctor’s office at 8 am. I began to feel lightheaded, started seeing spots, and got a pounding headache. The nurse took me back and said the prep may have caused dehydration. She said IV fluids would help. She had trouble locating a suitable vein for IV due to dehydration. After finally finding a good vein and starting fluids, the side effects subsided. The taste isn’t pleasing, I downed the prep both times in one gulp to avoid the taste. My doctor said the prep worked and I was clear for the exam. Unfortunately, it’s 11 pm, and I still have diarrhea. Hoping it’s gone by tomorrow. The stuff works, but for me, it’s harsh!"

Magnesium sulfate / potassium sulfate / sodium sulfate for Bowel Preparation "The Suprep bowel prep, to me, tasted horrible. I was so nauseous and wanted to throw up just from the taste alone. 10-15 minutes later, the nausea got worse and I felt like I had Montezuma's revenge (diarrhea suffered by travelers)."

Magnesium sulfate / potassium sulfate / sodium sulfate for Bowel Preparation "Now I know what it feels like to have cholera. Seriously. Ever seen the TurboLax scene in Dumb and Dumber? Well, this is worse. It tastes like chewing aspirin and immediately gave me a headache and nausea. The diarrhea started about 30 minutes later and hadn't stopped by the time I had to take the next dose. Golytely made me horribly sick to my stomach, but I'm not sure that this is better. Even with this, I had to starve myself all day. Next time, I'll just starve myself for a few days."

For Bowel Preparation "First off, this is not as bad as the Miralax or the Go Lightly. Will never look at Crystal Light or Gatorade the same again. Make sure to drink plenty of water because you just drank Liquid Drano. Everything will be watery for a while. No cramping like other stuff or explosive diarrhea. I suggest you buy some flushable wipes. You will definitely be on the toilet for a while. Keep hydrating."

Magnesium sulfate / potassium sulfate / sodium sulfate for Bowel Preparation "This is the best prep by far. I did the gallon stuff and vomited like you wouldn't believe. I did the Miralax Gatorade one and vomited all the time. This was a piece of cake. No vomiting at all. Lots of drinking with this. Started at 8 a.m. and the diarrhea started about 15 minutes. It quit by noon at the most. I take the last bottle at 8 p.m. I don't expect any problems either. I'm 69 and a semi-invalid and I made it to the toilet in plenty of time. Mine was berry flavored and didn't taste bad at all."

For Bowel Preparation "The whole experience isn't as bad as it sounds for the most part. I came into this extremely nervous and anxious over the prep. I haven't had a bowel movement in 3 or 4 days up to this point. I took Dulcolax at 2 pm. I took Zofran at 3:30 pm. Started prep at 4 pm. Finished prep solution at 4:20 pm and then began the 32 oz of fluids afterward. I can best describe the taste as extremely powerful. It tastes like cherry mixed with ocean water and soap. To get through the awful taste, I sucked on Warheads in between gulps. The sour flavor helped disguise the taste somewhat and immediately got rid of any of the taste of the prep post-drinking it. I chased with sweet tea. Highly recommend the sweet tea. It cancels out the flavor nicely. I had a bowel movement right away within the first 30 min. And the whole experience starts as explosive diarrhea. I even had to clean my toilet and toilet seat because it hit the water so hard it splashed out. Lots of bloating. No pain. Steady peeing out of butt."

Magnesium sulfate / potassium sulfate / sodium sulfate for Bowel Preparation "First off, I recommend you begin drinking this on the toilet. I also recommend disposable briefs for when you do finally leave the bathroom to catch the explosive, uncontrollable diarrhea that you’ll experience. Took this as prescribed for my colonoscopy. I tried this with both water and ginger ale; neither was very palatable (pretty disgusting, actually), but it gets the job done. Works extremely effectively."

Magnesium sulfate / potassium sulfate / sodium sulfate for Bowel Preparation "Doing this bowel prep for EGD/colonoscopy tomorrow. Started with a pre-cleanout Wednesday night with a 10 oz bottle of Mag Citrate. Pretty much cleaned out from that. Was told by MD (due to my severe constipation) to be on clear liquids Thursday and Friday. Literally felt like I was going to kill for food. 3 pm. Mixed the first bottle of bowel prep with Sprite. Followed others' advice and had it all chilled in the fridge. Worked on my 32 oz of lemon-lime Gatorade now. Tummy already making diarrhea noises. The drink was nasty. Plugged my nose and chugged it down, followed by some chugs of Gatorade, brushed my teeth, and chewed some mint gum. Will update..... dun dun dun."

Magnesium sulfate / potassium sulfate / sodium sulfate for Bowel Preparation "I had constant explosive diarrhea for four months (7 to 9 explosions of diarrhea daily with no solid food). Took Plenvu, which is 16 oz of med followed by 16 oz of water the day before and morning of the procedure. Thought I was going to die, the pain and cramps were so bad! The mango taste actually tasted like rotten mangos. After all of that, the colonoscopy had to be canceled due to incomplete cleansing of the colon. Found out four months later the CT of the abdomen was misread, and I actually had 2 bowel obstructions! The colonoscopy prep, as well as the colonoscopy, could have seriously injured me because the radiologist with supposedly 30+ years of experience “missed” 2 bowel obstructions! Changed gastroenterologist and changed prep to Suprep."

Magnesium sulfate / potassium sulfate / sodium sulfate for Bowel Preparation "Tastes awful. Better to drink it all down in one go rather than taking small sips. Shat myself a little later because I thought it was only gas. Spent the next 45 minutes shitting liquid."

Magnesium sulfate / potassium sulfate / sodium sulfate for Bowel Preparation "I've been disabled for 3 years. I am on pain medication. I don't really eat more than one meal a day. The doctor was aware of my medication and had a Barium CT prior, so it showed some stool, which I guess is normal. He didn't seem concerned when ordering the endo/colonoscopy Suprep. I had to have fluids the day of starting the prep. I even started an hour early, the taste almost made me want to vomit. I used candy, juice, you name it... About 45 minutes in, it started. I'm doing the endoscopy for my pain in my abdomen, but I figured with family history, I would do a colonoscopy. 4 hours later, the second dose was even harder to get down, I was going all night. Still, I was unable to do the colonoscopy. Now I'm home with constant diarrhea. Never again. The thought of that drink makes me gag."
