Butterbur

I"m starting Butterbur extract tonight, 75 mg twice a day.  My neurologist thinks it might help with the migraine prevention.  In addition to the B2 400mg, Propranolol, Nortriptyline, and Topamax. I'm also taking Magnesium.  I'm on week 2 of the Prednisone which seems to be helping with the rebound headaches.  I haven't taken any pain meds in two weeks :)  WOO Hoo!  And I only have 4 days of school left.
