1st time today had a colonoscopy.  Reading others experiences with this procedure makes you realise everybody is unique. I have had sedation before, but with an endoscopy and I went out like a light and didn't feel a thing. This was a completely different ball game.  Taking Moviprep was not easy for me as I am not a big drinker and it does taste foul in my opinion.

Hand on heart, the actual colonoscopy was painful at times.  Don't know whether I was not given enough sedation that I felt pain, and had to have gas & air as well during the painful bit.  

At the end of the day, some discomfort is a small price to pay when the outcome could have been a whole lot different. Being 77 years young with more chance of cancer the older you are, I was so grateful when they said I had no cancer, nor polyps or diverticulitis.    I would say to others, go with sedation and take the gas & air as well.  I'm convinced that had I been given a stronger dose of sedative, I wouldn't have felt anything.
