As a grizzled veteran of the operating room, yet no doctor, I would NOT take Tylenol 3 prior to doing ANYTHING that would require me to make judgement, especially snap judgements. It will also cause nausea and dry mouth is most cases. It is a good product but not to be triffled with. Any pain killer that is not OTC (and some that are) really have a tendancy to do funky things to your thought process. Thus the little stickers that say "May Cause Drowsiness" "Don't operate heavy machinary" etc. Or as Bill Murray said in Stripes "Its not so much the drugs but all that cough syrup I had this morning"!
I take a few Naproxen/Advil around noon time when I have a game that nite. It is an anti-inflam more so then a pain killer, but it does do wonders. I save any pain meds for after the game.
Now, if you would like to know the finer points of say Oxycontin v Oxycodeine v Tylenol 3... I MAY know a guy.............
