I had a migraine but I took excedrin and it's gone. Amazing, NOTHING before has ever been 100% effective. Started out with acetaminophen, that didn't work, then ibuprofen (which I can't take anymore because it causes emotional lability), still no dice, caffeine, nope, aspirin, naproxen, still not working. Acetaminophen, aspirin, and caffeine, three drugs that never did anything before, when put together magically beat the crap out of my headaches.
