>Can you please tell me if the Tylenol pain killer has Caffeine in them?

no, Tylenol has no caffiene, but the acetominophen is hell on your liver.
Excedrin has caffiene.  i'd take aspirin, if i was desperate, but the banana
peel trick usually works for headaches -- don't laugh.  peel a banana, and
put half of the peel against your forehead, and the other half on the base
of the back of your skull, and lie down for 15-20 minutes.  you'll feel better.
