headache
"I have been a suffering from migraine headaches for 20   years. I've tried EVERYTHING. My experience has shown if you take 2 tablets of Fioricet at the onset of one, you will do yourself a huge favor. It works. It may not eliminate your migraine but it will make it tolerable and less severe. Like others above, you have to be careful about how much you do take. I've found if I had a bad headache and have taken several pills, I have to then ween myself off of it by taking one pill every 4 hours over the next day or so to prevent a rebound headache. If you take many of these to relieve a headache, I recommend taking a few when your headache is gone to prevent a rebound. I make sure I carry my Fioricet with me at all times."
