I had the exact same thing done three weeks ago. The oral surgeon gave me oxycocet (codeine + acetaminophen) but it made me sick to my stomach, so I didn't use it. What worked well was a combination of extra-strength acetaminophen (Tylenol) tablets and ibuprophen, along with the antibiotics I'm sure your doctor gave you. I'm a pretty big guy, and with 2 tylenols and 1 (big) ibuprophen every 4-5 hours I wasn't in a great deal of pain. Also very important is that you ice your cheeks religiously. This goes a very long way towards reducing swelling and bruising. Seriously, ice the hell out of your cheeks the first few days.
