I'm going to take the pills instead of drinking the liquid prior to the colonoscopy. I know a couple people at work who had horrible reactions to the liquid (extreme diarrhea, nausea) but no problems with the pills. Another person I know didn't experience much of anything unusual taking the pills, but was "cleaned up" fine for the scope. With my work insurance the liquid stuff is free, and the pills cost $15. Well worth it to avoid possible nausea IMHO.
Geez, this reminds me that I have a couple 50+ tests to schedule in the next few months. I've been putting off one particular exam that was ordered by my Dr early this year due to some questionable growths. Maybe I've been sticking my head in the sand because I so do NOT like anything to do with doctors, examining tables, needles, backless gowns, and cold speculums. This thread reminds me that all of this is still better risking a lot worse.
