I was sedated when I had my wisdom teeth removed, but I wasn't completely asleep. I had WANTED to be completely asleep, but due to a medication allergy, they wouldn't do it unless I was in a hospital. So, I opted for not being totally asleep, but just really, really out of it. It's a weird memory because I remember people talking to me, but I don't remember the procedure at all and it felt like I was only there for about 5 minutes, when it was actually a LOT longer. If you don't want to be completely "under", maybe this would work for you.
