I don't work in GI, so grain of salt here, but iirc colonoscopies are usually just done under sedation - so you might fall asleep, but you might just be drowsy and too high to care. This is as opposed to general anesthesia, in which you are 100% out, and intubated so a machine can breathe for you.
There's always some wiggle room depending on patient preference though. Generally if it's a procedure you have the option in, take the least invasive option you can tolerate. General anesthesia's fine until there's a complication, then things get bad fast... rare, but much less rare than complications with sedation or local.
