I used to have about one day every 2 weeks when I DIDN'T have a headache. My doctor put me on grapeseed extract which is an natural antiinflammatory and the headaches went away completely. PLEASE try this stuff. Sadly it upset my tummy (I am allergic to grapes) so I switched to green tea extract, which is almost equally as effective. I now get a headache about one every 2 weeks and so far it has not been particularly bad. Green tea makes your blood pressure go down so I have to take it at bed time, this way I am fine. I cannot recommend this stuff strongly enough!!!!!
