migraine
"I have used this drug since 1979 @ age 27. Two day weekend headaches after a rough week were frequent (about 15-20 headaches/year) over next 10 years. They laid me up for hours or days. If taken within a few hours after a headache began, fiorinal is very effective. Wait a day and pain is partially reduced but lingers for 24 hours or more. Headache frequency gradually declined with aging. At current age headache frequency is down 95%. Fiorinal was a great help to me."
