Melly, yes, I've had several MRIs, and at least I know I have a brain, LOL!! And I've tried topomax, but it seems it works best (or any other migraine meds), when I have an aura and know I'm gonna get one. But I don't get auras nearly as often as I used to when I was in my teens and early 20s, so I usually just try to stay unconscious as long as I can. My aura is the sound of a stick breaking inside my head. Some say they smell things, others taste things...do you get auras?
