It really depends on what kind of anesthesia they use and how much. My mom is a medical assistant in the G.I. department of a hospital, and they happen to use propofol. Propofol is preferred by a lot of physicians because they can wake you up more quickly and it has fewer side effects. For example, less than 1% of people get nausea from it. I was unfortunately in that 1% when I got my wisdom teeth taken out, but they usually use much smaller doses for procedures like you're getting (endoscopy, etc.). So most likely you won't have any issues. My dad actually had that done recently and they didn't even give him enough to make him completely go under, he was kind of 'in and out', but he didn't feel any pain or anything.
So long story short, it'll likely be pretty quick and feel just like you fell asleep for a short time (if you completely go under). You might be a bit drowsy for a couple hours afterward (which is why you shouldn't drive til the next day to be safe), but otherwise it's not bad.
If you want any more details about the procedure, I can ask my mom about it, so feel free to PM me!
