bowel preparation
"I wouldn't normally review this type of thing, but I had read every horror story on the internet before I took it. It didn't taste "good" and everyone is different, but it was nowhere near as awful as I expected. This is not medical advice, but as other people have suggested:
1. chill it so it's cold when you drink it
2. use a straw
3. As  per my doctor, I rinsed my mouth between glasses with ginger ale
4. Based on what I'd read, I ate a low residue diet for the 4 days before (toast, bananas, jello, yogurt, applesauce) and was done with the process in 3 hours.
5. Do some stretches to move your stomach around.
My problem turned out to be revealed thru the endoscopy, not colonoscopy. But this wasn't among my top 25 worst experiences in life"
