I get hormone-linked migraines as well. (Weather also affects them.) I used to get them a lot more often, but I now take feverfew. I still get a couple a month, but the in-betweeners are almost non-existant and rarely turn into migraine hell. The headaches are about the same as they were when I was taking Elavil, and later Prozac - two anti-depressives which also work on migraines. No nasty side effects with the feverfew, though.
