migraine
"I've had almost daily migraines for a quarter century.  I am almost seventy and they are finally starting to taper off some.  



At one time or another most every possible preventative and treatment in the book -- and a couple outside of it -- were prescribed.  I tried a lot of other stuff on my own.  The most consistently effective treatment was cafergot.  I'd say it worked at least 90% of the time.  The few times it didn't, neither did anything else."
