I’m a chronic sufferer n I also have hemiplegic migraines so triptans r out. I’m on 6 preventative meds including 600mg of Topamax a day. Has anyone else heard of taking a dose this high? Last month I had 17 migraine n hangover days. My neurologist says there’s nothing left to do but Botox n I’ve heard so many mixed reviews regarding this. Anyone have any thoughts?
