I used to get migraines in my 20s, and they were REALLY bad. They'd start out with seeing a dark spot in one eye, like the kind you get when you see a bright flash. That spot would get bigger until I couldn't see out of that eye at all. I knew I had about 15-20 minutes to get somewhere safe. When my vision came back in that eye, the pain would set in like a knife. I would take a big handful of whatever pain reliever was around, and start drinking liquor. Nothing helped, I'd sometimes pass out from the liquor only to be woken by the intense pain. I'd just whimper in a ball until it subsided, maybe a couple of hours. Those scared the shit out of me. Up until a month ago, I'd get a slight headache every other day, sometimes I'd wake up with a bad one. I started taking mega doses of vitamin supplements because of a new eating and workout plan, and I haven't had one since. I don't know if the vitamins are the reason, but it's the only difference I can put my finger on (I was getting them on the new plan without taking the vitamins). Fingers crossed that they don't come back...
