migraine prevention
"I was prescribed Topamax as a preventative migraine med. It was effective in significantly reducing migraine. However it gave me insanely severe sinus/hayfever symptoms. I couldn't leave the house because my nose was running like a tap. I was sneezing all the time and totally stuffed up. I got all the other usual digestive upset side effects, but I could live with those as they seemed to reduce as time went on whereas the sinus problems intensified."
