For Bowel Preparation "I wish I would have found this page prior to my doing this. NEVER AGAIN. I couldn’t take the “Go-Lytely” years ago, so was happy to hear of a tablet prep. I started the night before. During the day, I had toast and chicken broth and jello for lunch. Kept hydrated. Drank 150 oz prior to prep. Took the tablets and had one bowel movement an hour later. Another hour later, but had lots of noises from my stomach. Today, I woke up at 5 AM and started taking the second dose. 15 minutes later, I started throwing up. Kept trying to get the tablets down, but they all came up. I was throwing up yellow bile for the next few hours. My son had to pull over twice on the way to my procedure for me to throw up in the car. Got to the procedure, had a nice nap, and was woken up to say they couldn’t do it. (I had warned them that I didn’t think it would work). 12 hours later, I’ve had Sprite and iced tea to drink and about 10 saltines. I still feel lousy and sick."

For Bowel Preparation "This was my 3rd colonoscopy prep. I used liquid preps before and had no issues at all. With Sutabs, I was sick as a dog, and it elongated the prep way longer than the liquid preps. I took my first dose at 6 PM and nothing until 9 PM. In the bathroom 20 times until 1:30 AM and then had to do the second dose at 3:30. That bout finished up at 6 AM, so I was up ALL NIGHT LONG! Plus, I felt horrible. My procedure was at 9:30 AM and that went fine, but I still felt sick the rest of the day and even the second day. I will NEVER take that crap for a prep again. NEVER!"

For Bowel Preparation "Took this prep the day before my colonoscopy at 5 PM as stated. Didn't start working until midnight! Took the second dose and nothing happened. Felt bloated and sick, and could not drink any more water than recommended. Had a colonoscopy scheduled but have to go back in a year because I wasn’t “cleaned out,” and yet I followed directions accurately. Next time will use the liquid form, what a waste of time!!"

For Bowel Preparation "One of the worst experiences I've ever had. The stomach cramps were debilitating and I expected to get sick. I was sick all night and the day of the colonoscopy. I wouldn't recommend this to anyone."
