I had mine removed when I was about 19. I was CONSCIOUSLY sedated (with pills), and I was nervous because I HATE the dentist. My dentist reassured me that I wouldn't remember it, that most people fall asleep. I remember being in the waiting room, nervous because I didn't feel any different (I had taken the pill an hour before). The receptionist let me take another one. After that, I only remembered the dentist saying "okay, we're going to stitch you up now". I remember nothing from the rest of the day. The days to follow were much worse than the actual "surgery". They give you a prescription for the pain, just make sure to stay on the soft diet as long as they ask. I think it might be nice to have full sedation, because they can snap you out of it better. It makes you nervous, but then it's over. You'll feel so much better after you've conquered it!
PS, I really enjoyed eating KFC mashed potatoes and gravy as I recovered :)
