I had all four of my wisdom teeth out at the same time. Back about 10 years ago now.
When I got there, they made me take my contacts out. Went into the room, had an IV
started. They have me nitrous oxide for about 5 minutes and it honestly didn't do a damn thing. Anyway, when they go to put me under, they say "count back from 100". Well, I got to about 97 and was out. It was the coolest feeling in the world! 99 came out just fine, but I remember 98 was like someone just pulled the shades down over my eyes! When I woke up, my contacts were in my eyes and my dad was the one who woke me up. I asked him how are my contacts in my eyes because I took them out. Well, apparently the first time I woke up, I put them in, and went back to bed. Don't recall that at all. They sent me home with Oxycodone. I never ended up using any of it because I was never in any pain. I took a short nap when I got home, and was back to doing normal things that night. Never affected me like it does some people. I guess I got lucky.
