migraine
"I come from a family where everyone has terrible migraines. When I started getting them at age 21, I resorted to taking loads of Tylenol with Pesudophedrine to "mask" the pain, which took a heavy toll on my liver.  Someone suggested that I look into the Triptan family of migraine medication. After going through a few different ones, I found Imitrex to be an absolute life-saver.  Whenever I feel one coming, I take 50mg and the migraine usually disappears within 30 minutes. If I wait a few hours to take it, the response time could be more like 90 minutes. With 10-15 migraines a month, Imitrex is essentially the only thing that allows me to function. I have not seen any real side effects."
