For Bowel Preparation "It's a lot to drink, but you can do it. I used a straw and just chugged it down. I did use the lemon flavoring packet. It really didn't taste too bad. My suggestion is that when you first feel an urge to go... go! This stuff works. My doctor had me take 8 oz every 30 minutes, after the first two doses, it started working. I spent the rest of the day on or near the toilet. An hour after my last dose, I was done. I did not have any cramping, nausea, or vomiting. Overall, not a pleasant experience, but this liquid is not too bad."

For Bowel Preparation "Low residue diet 3 days before the test--white bread (toast, PB&J), plain bagels with cream cheese, crackers, pretzels, eggs, chicken, etc. Had jasmine tea, two scrambled eggs with butter, white bread toast with butter, before 9 a.m. Mixed lemon packet in prep and put it in the fridge. For lunch, had DELICIOUS 'Zoup' chicken broth. Also, lime jello, Gatorade, and apple juice. At 5 p.m., took a Zofran to ensure the prep would stay down. Not starving by 6 p.m. when I started prep! It didn't taste nearly as bad as I had imagined. After every few sips, chased it with apple juice or Gatorade. Within 2 hours, was able to drink 1/2 prep. Did its job. At 3:30 a.m., did the 2nd dose of prep. Again, drank only about 1/2 in 2 hours. Because I had eaten so lightly and so low residue for days prior, this was all I needed! Nurse said prep was GOOD! So, I didn't have to starve myself the day before, and didn't have to drink the gallon of prep! Hope this helps!"

For Bowel Preparation "Honestly, it's not so bad - not my favorite thing to drink, especially in such a large quantity, but if you just chug it down 8 oz at a time, it's doable. It does work as advertised - I was on the toilet within an hour. If this is what it takes to be checked out (colonoscopy), it's worth it to make it easier for the doctor to see what he's looking at. Good luck!"

For Bowel Preparation "Unfortunately it didn’t work well for me. I’m 47. Have had growing gastro problems which prompted the advice of colonoscopy. I started it an hour early and took it from 5-10pm. I could not go any faster. I was severely bloated (which is part of my ongoing problem) and it took 3 hrs for the bowel movements to begin. At 2:30am I woke up feeling dizzy. I exploded on the toilet (finally - as they watery stools were slow to come out actually) but then broke out in a sweat and and had to throw my clothes off and everything turned white as I stumbled 6 feet to my bed face down. I passed out and became “deaf” I couldn’t hear anything- not the fan in my room - just the ears hissing and ringing sooo loud that is all I could hear. About 5 minutes passed and I slowly heard the fan and my ears gradually cleared and I was totally limp. I pulled myself up to the pillow as I was sideways on the bed."

For Bowel Preparation "Gavilyte made me acutely ill the first time I took it 15 years ago for my first colonoscopy and also my most recent in October 2018. Five years ago I used a Miralax prep for a colonoscopy with much better results and no acute illness. In October 2018 the doctor's office insisted I go back to the Gavilyte. I informed them it made me sick. They gave me ONE Zofran for nausea for their TWO stage prep. I got through the first part of the prep that started 4 hours after taking Zofran. But when I started the second stage of taking the remaining half gallon of Gavilyte at 2:30 am the Zofran had worn off and I became acutely ill. Not just with vomiting, but with malaise so severe from head to toe that I was calling out to my husband for help in between head-in-the-toilet vomiting. They called off the colonoscopy and the week of preparation was for naught. Now I have to repeat the process. At least this time it will be with Miralax NOT Gavilyte."

For Bowel Preparation "After taking half the bottle, woke up in the night with throat tightness, high heart rate and high blood pressure. Had to go to the ER. Possible allergy to peg3350 which is in the makeup of this stuff."

For Bowel Preparation "My last colonoscopy was in November 2017. I just had another colonoscopy today February 16, 2023, and I must say it was much easier to drink this time. Adding the lemon flavor pack, I think really helped, as well as drinking it very cold from the fridge and using a straw. It wasn’t as hard as the first time back in 2017 when I didn’t have the flavor pack. The second day was harder, but all in all, it worked, and the colonoscopy went well as a result. The only thing is it is a lot to drink and I’m not sure if I one-size-fits-all prescription is necessary. Somebody who is 5’5” and weighs 120 lbs may need less of the drink than a 6’2” inch tall man who weighs 220 pounds."

For Bowel Preparation "Went in for prep and asked: “My last colonoscopy was 10 years ago, have you done anything since then to make the prep fluid more tolerable?” Of course, they had not. This is how you know nobody give a damn about patients. They don’t care enough to improve the revolting salt water pre-procedure solution. It can be fixed, they just don’t bother. I wonder how many people have died because they dread this prep, and therefore forgo the entire procedure."

For Bowel Preparation "This is the worst God awful tasting stuff I've ever had. They say you're supposed to drink 8 oz every 10 minutes it's 5:30 I've been drinking this since 2 and I only got half the bottle gone it tastes horrible and it's not working yet"

For Bowel Preparation "This is not what my doctor prescribed, but the pharmacist didn't have what he prescribed, so a substitution was made. A horrible substitution. The taste, even with the lemon packet, was salty and not at all good. Still, I gulped down 3000 ml of it before I just could drink no more. The reason I could drink no more was because I was constantly on the toilet. I felt like I was urinating out the wrong hole. When the pain just got to be too much, I stopped. I consumed around 3000 ml, which proved to be more than sufficient for a 150# woman. Yes, it worked, but my rectum was so chaffed that I made my daughter run to the store at 10:00 pm to get me diaper rash cream, which freakin BURNED when I applied it. When things calmed down with my bowels, that got better, but I had painful diarrhea for days after the colonoscopy. If your doctor prescribes this, tell him or her that you refuse to use it. If you can't get a different prep, get a different doctor."

For Bowel Preparation "This is the same as the other one with electrolyte listed but its nasty; to drink a gallon is horrendous. They need to make a better tasting type of drink or flavor pack or something. I have been suffering from constipation for years and to drink this prior to my test tomorrow is just beyond me. It's been since 9:30 am and I'm still drinking it. The doctors said if you get nauseous etc etc drink it slower and it will still do the job."

For Bowel Preparation "This stuff definitely works and I will definitely give you the best advice you will find on actually being able to "enjoy" having to drink this stuff. I used 2 gallon-sized packs of Starburst strawberry drink mix which is pink, not red. It covered the taste of the product completely and in fact, it worked so well that due to a mix-up with my scheduled colonoscopy having to be pushed at the last minute to the following day, I had to do the entire process of cleansing two days in a row and the strawberry drink mix didn't affect the colonoscopy at all. Just don't use any drink that is red or purple."

For Bowel Preparation "I had 3 glasses, and after the third instantly felt nauseous and my stomach was cramping immensely. I feel lightheaded and horrible. I was not feeling this way before the prep so I know it was from this. I called and canceled after feeling so horrible. I was so nauseous I couldn’t even finish it. The taste is doable but the way it made me feel was horrible and I wasn’t even halfway through."

For Bowel Preparation "I had an impaction so severe that I thought I had appendicitis. I was devastated thinking that I was headed to the ER for surgery. They gave me a script for GaviLyte and within 35 minutes of drinking 8 oz every 10-12 minutes, I was on the toilet for about 3 hours straight. My stomach was cramping badly before I finally went, but when I started, it was like relief I’ve never felt before. By the time I stopped going from the GaviLyte, it was like water with hardly any color. It turned my day around very quickly from feeling like I was looking at certain surgery from so much build-up pressing against my appendix to the best relief ever in a matter of hours. I highly recommend it. Be sure to read the entire side packet of instructions."
