I have had all my flex sigmoidoscopies stone cold sober, first one at age fifteen, and those are no fun. All the colonoscopies though (various types of sedation for each), went great - no pain or real memory of it afterward. (Same goes for the upper endoscopy I had.) Even though you might not technically be "unconscious", if you have any sedation at all, you will most likely not feel or remember a thing.
My very fist one they used Demerol. Started with one shot, and as soon as the doc got in with the scope, she saw me wince and said, "Give her another shot of Demerol." After that I was high as a kite and feelin' NO pain, if you know what I mean! They could have done anything to me at that point and I would have taken it with a sleepy smile, LOL. I don't remember anything after that.
I'm sure you'll do fine. Just tell them about
your concerns, and they'll take good care of you!
