With old school sedation I think it might be worth avoiding it. But with propofol you are out like a light, and then wake back up just as fast when they turn it off -- and it feels like you just had a nice nap. Aside from feeling a bit groggy for a few minutes, you just get up and walk out the door and go about your day. Personally, I do not think I'd volunteer for 7/10 pain just to avoid that.

My first colonoscopy was without anesthesia, and it was as described above. A little uncomfortable on the one bend, but I don't even think I would put it at 7/10 (perhaps a 4 or 5—but not a sharp pain, mind you).

Definitely enjoyed the following times with anesthesia because, of course 0/10 as far as I know. Also, anesthesia just trips my mind—how seemingly time travel (going forward in time) seems to be involved.
