@januaryjane I too had a somewhat inconclusive colonoscopy due to the prep not being as thorough as it should have been. I got so sick in the middle of it that I had to stop drinking the liquid for a couple of hours. The next time my gastroenterologist had me eating easily digested foods starting on Sunday for a Wednesday colonoscopy - no raw fruit or vegetables. Then I had to go with just liquid starting Monday night.
Colonoscopy prep is a really miserable experience, although my first one was more tolerable. If you do three days of liquid only it probably will be easier. Will you still need to do the typical prep?
