For Bowel Preparation "Despite the side effects of nausea, vomiting, and taste, I have to keep in mind that it was beneficial for my overall health. I am a 4-time survivor of colon cancer. I would rather spend a few days out of my life enduring this than going through chemotherapy and losing the battle to cancer as my father and grandmother did."

For Bowel Preparation "Had to have a procedure yesterday which required MoviPrep to completely clear me out. I was fortunate enough to receive the lemon version which caused me to constantly gag with every slight sip. It’s absolutely disgusting, and I feel for anyone having to take it. What I did to get the best success with this was to mix it with Sprite/7UP. I’d do 60% of my glass with the MoviPrep and 40% with Sprite. Before I started mixing it with Sprite, it took me two hours to go through two glasses. After mixing it with Sprite, I was able to comfortably drink it when it was time to get through it. Make sure you have wipes rather than toilet paper, you’ll need them. Best of luck with whatever you need this for, you’ll smash it. This will ensure you are properly cleared out, trust me."

For Bowel Preparation "Started tonight with the first dose. I’m not good with liquid medicines at the best of times, but this stuff is horrid. The taste I can cope with, it’s the texture and how it feels in your mouth. Only managed 50% before giving up, as it made me vomit, so I didn’t know which end to point at the loo. Will try again in the morning and add more water to the mix to see if that helps. Can you design a pill version, please."

For Bowel Preparation "I'm 29, and this is my second time in less than two months having to take MoviPrep. They couldn't complete the colonoscopy the first time around. Everyone has different side effects, but for me, it makes me so sick. I have to get a colonoscopy every two years, and this terrifies me. I'm very petite, and my stomach just doesn't hold out to 2L of it. I took the first batch at 5 pm, and it took me 2 hours. The second batch is not so easy. I started at 9 pm, and it's now 10:30 pm, and I can't stop vomiting. I've drunk half of the second batch, and my bowel is clear, so I'm hoping that will be enough for my colonoscopy tomorrow. The no eating and sitting on the toilet doesn't bother me at all, I wish there was something less nauseating!"

For Bowel Preparation "So I've taken MoviPrep Orange, and at first it's not too bad, sort of a salty orange flavor. But then you start to notice the thick, gloopy texture and honestly couldn't stop gagging, absolutely foul taste. Took my first liter at 4 pm, and at 5:30 pm, the movements started. Attempted to take the second liter at 8:30 pm but only managed to get half down. Currently 11:55 pm and still making trips to the bathroom every 15-20 minutes... I'm only a tiny 18-year-old girl. Feel so bad. Definitely don't need the full 2-liter dose, but we'll see tomorrow. This is my third bowel prep, and I will not be doing it again."

For Bowel Preparation "I'm 19 years old, and this is my second time doing this. First time, I had the lemon, but the orange tastes a bit better. I'm now into my morning dose, but I just can't hold it in anymore. I gag after every sip, starting to feel dizzy again, my cheek is cramping up, and I can't even take the smell anymore... If they ever start producing this in pill form, I'll be the happiest man alive."

For Bowel Preparation "Drink MoviPrep chilled and through a straw. The taste is a salty lemon, vile, awful, thick sludge. Use a chaser of ginger ale or white Gatorade. It’s easier to just chug through a straw. Do not. I repeat, do not go far from the bathroom once you start drinking. It started working within 15 minutes, and I had fasted for 26 hours already. And low fiber before that. I got chills, nausea, gagging from the drink and the taste. The chills lasted three hours. The bathroom trips lasted for 4 hours or more but slowed down. You cannot control it. The urge comes, or sometimes does not come. It just happens. Then it’s time for the second dose. I could barely get through the second one, and I’m more nauseated even after a prescribed anti-nausea pill I had on hand from a previous issue."

For Bowel Preparation "As soon as I smelled the MoviPrep and took the first drink, it reminded me of Lemon Pledge furniture polish. It has a strong taste and seems to get stronger with each gulp. I started at 5 pm, and by the 2nd 8 oz dose, it had started working. Stay very close to the toilet. Started the second phase at 8 am the next day and had a very difficult time drinking it. I almost vomited a few times. I could not finish the last 6 oz. I just couldn't. I did use apple juice to help, and I took a sip of juice, then gulped the mix, then another drink of juice, and it helped get it down. When you are finally going clear yellow fluid, you are clean according to my doc. That happened at the end of the 3rd dose in the morning. It worked perfectly for the test."

For Bowel Preparation "I wish I had read the reviews before taking MoviPrep. Firstly, the taste is vile. I don't know how, in this day, a medication can be so bad. Much respect to those who have posted they drank it in 10 minutes! It took me 2 hours, and even then, I had to stop myself from gagging and throwing up. My best advice is wet wipes (much softer than loo roll), and my trick in the end was gargling a strong mouthwash until my mouth was numb and drinking as much as I could - and repeat. Good luck. The second dose was just as bad. I need to man up, I know! But although very effective - vile, vile, vile...."

For Bowel Preparation "I was supposed to take 2 liters of MoviPrep at 5 pm and another 2 liters at 8 pm. After taking 1.5 liters, I became unwell with severe nausea and vomiting. It was impossible for me to take any more as I was vomiting it all back up immediately. Unable to go ahead with colonoscopy as I was unable to take enough to clear my bowel. The taste was horrendous, very salty."

For Bowel Preparation "First glass okay, then started to vomit. Forced myself the other half a liter due to operation, however, could drink no more as I was terribly ill, vomiting. My operation had to be postponed. I am now waiting an alternative. MoviPrep is gross to drink, but does make the bowels move."

For Bowel Preparation "Just finished split prep for colonoscopy this morning. Not as bad as I had feared - chilled solution, used a straw and chasers, finished with mints. Could not drink the final glass (knew I would vomit), but was well cleaned out. Clear your schedule and have good reading material handy, and it's not too bad."

For Bowel Preparation "I just finished my first liter of MoviPrep for my colonoscopy tomorrow. It's disgusting tasting and very hard to swallow, I'm constantly gagging. It does exactly what it's supposed to, though I feel like I'm peeing from my butt, and it's definitely cleaning out my system. I'm dreading the next liter in the morning."

For Bowel Preparation "Absolutely the worst stuff I have ever tasted. It would be better if it was plain, not lemon flavor. Unfortunately, I have just taken the first dose and vomited up at least 8 ounces of it. May not make the procedure because I am not sure I can take the second dose. Pure torture."

For Bowel Preparation "This is my first time having bowel prep for the colonoscopy. I started my first prep around 4 pm after my lunch finished at 12 pm. I finished one liter solution in one attempt, but it was an unbearable taste. My bowel movement started around 5:30 pm. Do not ask about the poo, it is almost water and continued until my second dose started at 8:30 pm. I was really disgusted with the taste. During my first glass of the second prep, I literally vomited, I still kept continuing until I finished the second prep. My last prep is the following morning at 8 am. Let's see how it goes..."

For Bowel Preparation "I'm 18 and having a colonoscopy tomorrow. They put me on MoviPrep and it's working! Started off chasing it with some ginger ale, but after the first 8 oz, I was gagging. I bought some melon Powerade and it went down easy. Just add some ice and mix the MoviPrep in, and it went down like a charm. I still haven't had the second 'installment' at 4 am, but I'm sure it'll go down just as easy as the first dose. Plain, it tastes wretched like this lemony salty gooey water, but mix it up and you'll be fine."

For Bowel Preparation "I was prescribed MoviPrep for a colonoscopy, which I took last night at 6 PM. It tasted absolutely horrific, it tasted like Alka-Seltzer with lemon flavor. It is very salty, and it made me feel sick - I felt like I was going to vomit for an hour. It finally worked, and I felt a lot better this morning. I know I had to take it again, so I added ice to the solution and made it very cold, and it was a lot easier to drink and it didn’t taste as bad, it seems to be working. The key here is to make it very, very cold, and it does not taste as bad. Also, some people have mixed it with Crystal Light and found it to be more pleasant."

For Bowel Preparation "Was due to take 2 liters of MoviPrep before a colonoscopy. Took the first liter without much trouble at 7 pm and, despite gurgling, did not go to the toilet before going to bed at 10 pm. Attempted to take the second liter at 6 am but only managed to drink about half of it before I was projectile vomiting the solution plus stomach bile everywhere. Wasn't able to take anymore and still had very minimal bowel movements, so had to cancel my procedure."

For Bowel Preparation "18, from the UK, so I got this lovely stuff for free. First, I smelled it, and I was pleasantly surprised at the fragrance. I thought this wouldn't be so bad! I made up my first liter of MoviPrep in good spirits and took the first sip; it was absolutely awful. The best way to describe it, I think, is if you fully dissolved salt into water and then tried to put as much sweetener in it as possible as if the salt would be masked! Along with that artificial lemon taste you get from things like Soothers for sore throats, I was gagging every mouthful or sip. The only reason I gave this 3/10 is because after about 2 hours of starting the first liter, I was able to flush my intestines out with a powerful gush."

For Bowel Preparation "I had to take this for a colonoscopy. Having not been allowed to eat all day the day before the examination, I was quite apprehensive about putting this strange-smelling, lemony stuff in my mouth. Needless to say, I found it incredibly hard to drink. It took me around 2 1/2 hours to finish the first liter, starting at 5 pm and finishing (eventually) at 7:30 pm. It took about an hour for the medicine to work properly, after I was stuck to the sofa with bad stomach cramps. The second liter didn't go down well at all. I was very bloated and felt like I was going to vomit, which I didn't want to do, as then it would have all been for nothing. It's 5 am now, and still half a liter to go. Hoping it will be okay as I'm still stuck to the toilet."

For Bowel Preparation "Well, it did what it was supposed to, but tastes so bad. I got through the 1st liter okay. I gulped it down. Bowels were moving about an hour after the first 8 oz. I had to drink a second liter several hours later and just couldn't do it. The taste is that bad. I threw up probably half a liter of it. Anyway, it cleaned out the bowels."

For Bowel Preparation "I took MoviPrep four years ago prior to a colonoscopy, the final glassful made me sick, but it did the job. In May of this year, I needed my colonoscopy repeated and again took MoviPrep. Based on my earlier experience, I expected to be sick toward the end, but this time was much worse. I managed to get the first batch down, but as soon as I got out of bed the next morning, I vomited. There was no way I could drink another liter! I was sick four times and had to cancel my appointment. When it was rearranged, they gave me Picolax, which I was able to take with no side effects. I’ll be asking for that in the future."

For Bowel Preparation "I'm 19 and taking MoviPrep for my first colonoscopy. Or should I say was taking it. First glass was terrible, but with a plugged nose and a strong chaser, it was possible. The second glass was absolutely horrible. About halfway through it, I vomited twice, got the chills, and called my doctor to cancel. I'm rescheduled with a different prep (with only 4 total tablespoons of prep and a ton of water!). The rest of the day, my stomach was upset and came close to vomiting multiple times. It's now 12 (did the half a liter at 5), and the bowels just started moving. Would not recommend, it's terrible, and there are better alternatives!"

For Bowel Preparation "I started my prep at 10:00 tonight, 3/6/2015, late due to the storm and having to travel 6 hours away. First off, this isn't my first and won't be my last. I started just on clear liquids on Tuesday so I wouldn't have a lot to come out. So I drank my first liter at 10:00 and not 5 minutes after my first 8 ounces, I was in the bathroom. I continued and got both liters down and have had some ice chips. It's 2:25 AM, I am still on the commode and it's all clear. I did have issues with vomiting this time, which is not me, I have these at least every three months. But overall, I am now hoping I am on the downside and can lay down and get warm. The chills are the worst."
