december, the thing you're talking about is acetaminophen syndrome. The alcohol and tylenol attacks your liver like no other...it's unbelievably bad for you.
do NOT take anything w/aspirin in it while drinking...only after a hangover...like way after. Some people have a reaction to aspirin that causes the brain to put an enormous amount of stress on the skull and causes brain damage. This is pretty rare and normally happens w/people who OD on aspirin based products. However, alcohol will exaggerate the affects of aspirin quite a bit.
Gatorade works b/c it's the same idea as eating fruit (bananas, tomato juice, etc.). There's pretty much ionized (i think it is anyway) magnesium, zinc, sodium, and then the additional sugars...that'll knock it down pretty well.
