Is there anything I shouldn't eat, drink or do after a tooth extraction?

[Enemy of One]

12 hours I got one of my wisdom teeth pulled, it hurts but the pain isn't too bad. I've cut down on smoking, I'm not drinking through a straw nor am I spitting. Now is there anything else I shouldn't do, also is there foods or drinks I should stay away from? Another question, does anyone know of something to relieve the pain other then pain killers, and how long will it take to heal?

Thanks in advance!
