Mama's Got a Migraine

For the second time in a week, I find myself with a migraine headache. I take a prescription medication called Axert that helps. But does anyone know any natural remedies or preventatives? I don't know what triggers my headaches even though I had my first migraine at age 5. Medication has come a long way since then, but the pills are $12 each after insurance! Share with me if you have any helpful tips or your own migraine questions.
