In colonoscopy, the prep is the worst part if you do it with sedation. The prep is just unpleasant because you spend so much time on the toilet.

For myself and many others, it's not really about the pain (supposedly there is little to none), it's just the unsettling thought of that scope so far up one's...

I was sedated with Propofol and that seemed to be routine in the facility I went to. It was a white fluid that came in through an IV. I remember saying to the nurse as I saw the propfol going in "that tingles..." and she said "that's normal", but it seemed to me that she said her answer before I finished saying "tingles", then a herringbone pattern visual from my tightly shut eyes, then nothing, and I woke as I was being wheeled out to the recovery area and felt no grogginess at all, seemed that only a couple seconds had elapsed from the time I saw the propfol (it was 20 minutes). Powerful drug.
