Experience can vary--I had all 4 impacted teeth removed at once and I stayed awake for it (my oral surgeons preference as I have asthma and he didn't want to put me under). It was more-or-less fine except that I had a reaction to the pain killers they gave me. I did have a lot of bruising and pain, but I bruise easily and I was 16 or so at the time. I know people who've had the teeth pulled and gone out and partied that night. My advice: they will probably offer you something for pain--make sure it's something you think you can tolerate. I'd plan on a recovery day or two just in case.
There was another thread on this recently with some detailed experiences:
