Please raise your hand if you've had your wisdom teeth removed.

Okay, I went to the dentist today, and he wants me to go to an oral surgeon and have my wisdom teeth and the tooth that's been giving me trouble removed (5 total). He suggested I have them all done at one time, but that it was up to me. So here's my question, if you've had your wisdom teeth out, what do I need to know? Should I have them all done at one time? What's the heal time on this? Anything you think I should know, short of "run screaming from the dentist and never, ever go back." ;)

*whimpers* I don't deal well with pain, and I'm not looking forward to this.
