I get them as well. My neurologist strongly suggested taking the pill for four months straight and then having a week off to reduce them. He said to talk to my GP about it and she said it was fine but to think about it first. I decided not to at this point. That being said, I can still get them during my period. I've found that Axert works best for me, it's one of the triptans like Imitrex. I also found that when I started taking an Omega 3-6-7-9 capsule my daily headaches and migraines decreased dramatically. I've been able to hold off on a new preventative for awhile, so you could give it a try. I haven't ever tried feverfew.

But talk to your doctor about it, there are a lot of options. Pain medication did nothing for me either, even prescription stuff. Hope you find something that works for you.
