migraine prevention
"I've had severe headaches/migraines about twice a month since I was about seven years old. As an adult, my headaches were brutal: 36 hours of feeling like I'd been shot in the left eye, and NOTHING helped.  I always had low-to-normal blood pressure until it jumped up post-menopause despite my being thin, active, a non-smoker, etc. The hypertension meds I tried either made my headaches worse or made me so tired I could barely get out of bed. Lisinopril also made me tired, but to a degree that I figured I could live with. A few months later, I realized I hadn't had a headache since I'd started taking it. Fifteen months later I am still migraine-free. Unbelievable!"
