Just a bit of perspective on the availability of/recommendation for sedation: In the US it is almost always either regularly done or at least offered. In Canada (KGH, specifically) and the Netherlands, it is almost NEVER routinely done or offered. Even when I was so ulcerated that I was screaming in pain and blacked out (pre-surgery), a full colonoscopy was done with no sedation. Yee haw!

Other than that experience -- which was HELLISH -- I have never had the sedation or even been offered it, and have never felt the need. It's not, you know, a FUN time, but when there is no inflammation it is only uncomfortable, not painful. The air being shot inside can be a bit crampy (think gas cramps), but they always remove it if it is too much.
And I agree with others, I like watching the screen! Hey, we have to get our kicks somewhere.
