bowel preparation
"This is my third colonoscopy.  Sure,  Suprep doesn't taste good,  but it's no where near as bad as the Phosphosoda stuff I had years ago with the first procedure.  That stuff was like drinking concentrated sea water. The Suprep was a walk in the park by comparison. 

The two day prep worked well for me and I think the bland,  low bulk,  low fiber diet two days before the procedure reduces the cramps and abdominal discomfort.  Thirty minutes after the first dose it started working.   I had a little nausea,  a few chills, but nothing major.  I have yet to take the second dose but don't anticipate any problems."
