Herbal Schmerbal

I am getting really discouraged. I've tried just about every pharmaceutical migraine preventative on the market with no results. And, now, I've been taking several herbal medications that are "known" to help with migraine prevention for awhile, and I am still getting migraines every day. I just don't know what else to try. I hate being sick all the time; I feel like I'm missing out on my life.
