Have you tried any migraine prevention meds? I was on Topamax for years and it did wonders for me! It drastically cut down the frequency of my migraines. The only migraine med I could tolerate that helped when I did get a migraine, was Amerge. I have since developed an allergy to it
Try what Wren said, ask your dr to prescribe more. Majority of insurance companies will only cover about 9 pills every month. When I switched over to my husband's insurance, BCBS, they would cover more per month...I was shocked!
Good luck,
