headache
"Fioricet is truly a wonder drug. I'm had migraines since I was 15 (27 now) and if you take it right when the headache starts, lay down for 30 minutes, you'll feel rejuvenated. BUT, Fioricet can cause rebound headaches (headaches that one gets when they are used to taking a medicine for a while), so while it may be hard to just take one pill when your head is throbbing and you have things to do, it will pay off in the long run. So try to alternate with other medicines in there so your body doesn't get used it. Because I rebounded from Fioricet which means I have chronic daily migraines = no fun. In conclusion, great medicine. "
