bowel preparation
"The worst bowel prep I've ever used.  I found the solution easier to handle by refrigerating  it before drinking. I don't know how anyone could drink it warm. 

I can't drink large amounts of anything at once so needed to take small sips. EVERY swallow made me want to gag. I am physically unable to vomit, but oh I wished I could. I was nauseated the entire 6 hours of prep. 

I spent most of the 6 hours (I took part 1 from 6 to 7 PM and part 2 started at 10 PM, finally exiting the bathroom after midnight) in the restroom and thought  I'd done well cleaning out my system. Much to my surprise the next morning, I still had dark runny stool. Worse, the DOCTOR reported BAD PREP RESULT with stool remaining so he was NOT ABLE TO SEE WELL. REPEAT"
