Anecdotes are not data, however I used to have one or more severe migraine headaches weekly. Debilitating migraines. I suffered pretty high blood pressure (which has a very direct relationship with cerebrospinal fluid pressure, which is why I mention this), but aside from that am very healthy and physically fit, exercise regularly, and so on.

I started medication to treat the BP -- telmisartan and amlodipine -- and my BP dropped from 150+/120+ to 115/80. The migraines completely disappeared. I still infrequently get the visual aura that would traditionally precede a migraine, but nothing follows. I haven't had a migraine in the years I've had my BP under control.
