bowel preparation
"Face it - prep for a colonoscopy is not and never will be an easy chore.  However, Colyte and its equivalents is much better than the older use of Phospho-Soda.  That is just plain nasty, upsets the stomach way more easier than Colyte, and it took me three bottles (with the third purchased at 2:00 AM) to get me acceptably clean resulting in no sleep that night.  For my next colonoscopy I used Colyte and worked much better.  That's what I now opt for as prep."
