bowel preparation
"Prepopik has been the most effective pre-colonoscopy solution I've ever used. Since my mother died of colon cancer in her early 40s I started to have colonoscopy tests early in my life. The large bottles of solution I've had to drink previously were unbearable to me. I've had to postpone tests because I was unable to drink the horrible stuff and "the day before" was always a nightmare.
This time the only medicinal potions I've had were two five ounce drinks which were actually not horrible. They did the job - boy, did they ever. Cleansed me of everything, including my dignity. Started to work after some two hours and did not cease. 
Post the procedure I had two bouts of diarrhea immediately after coming home, and then I was fine."
