bowel preparation
"So, I read the previous reviews with a lot of trepidation.  But my experience was pretty positive.  Is it something I want to do again?  No way.  But it wasn't intolerable as I feared.

The taste isn't good but bearable if you chase it with something else (ginger ale in my case).  As others have said, it's the water afterwards which is most difficult as you are already bloated.

My stomach started making noises around 15 minutes afterwards and within 45 minutes I was confined to the toilet for the next hour and a half.  But then it was all clear and we were good. The morning one was more limited as I was already mostly cleared.  Maybe another 45 minutes on the toilet.

The actual colonoscopy was a breeze.   Nothing to fear."
