Wow Quincy, that's very brave of you. Yes, when I awoke, I felt pain and was severely uncomfortable. I remember screaming to them as I was trying to remove the device, "It hurts! Get this out of me! Please!!!!" I couldn't imagine being semi-conscious during a colonoscopy.
I was given propofol I believe, but when I came to, they injected benadryl to knock me out again.
My wife and I go back in two weeks to get the results of the biopsy.
I keep thinking though, what if I awoke during the endoscopy? Wow, kinda scary...
