Anyone else here get migraines? My neurologist prescribed me Topamax (a preventative) and I have been taking it for a little while now. It seemed to be working pretty well, but I've had two migraines in the past three days. The current migraine was there upon waking and unaffected by food, drink, prescription pain killers, etc. I still have it over 10 hours later. So, are any of you on preventatives and still getting migraines? Two in a period of three days seems like A LOT for someone taking a preventative drug.
