migraine
"I get migraines every month or two that are one sided, typically coinciding with my period, and usually after I drink.  They aren't completely preventable with the drinking thing because a) they happen occasionally when I don't drink and b) I'm not going to stop drinking.  Excederine Migraine is definitely the best medicine I've taken for them, but it doesn't come close to eliminating the pain completely.  I've had migraines since I was about 10 or 11, and each one pretty much debilitates me for 24-36 hours, therefore I'm thinking of going for a prescription.  "
