I have about 2-4 migraines a month. Have had them since age 12. Not sure why they started then. I get them with aura though so I know when one is coming and if I take meds right away I can usually catch the pain before all hell breaks loose. It doesn't do much for the other side effects though. I don't think it has anything to do with my bp though. My triggers tend to be hormones, barometric pressure changes, lack of sleep, and allergies/sinus inflammation.
