migraine prevention
"I took Topamax as much as 300mg/day for 15 years and my last dose was 150mg at night. I recently changed to Lyrica which is also an anti-convulsant and am taking 100mg/day and find it more effective than Topamax without the memory and lost word problems. I discontinued Topamax because it slowly got to the point where I could not remember something for an hour. Topamax also was causing erectile dysfunction problems for the last 3 years. I do not have this problem with Lyrica.
In the end I was getting 5 or more migraines a week and now get 2 or 3 a week and expect to increase Lyrica to 300mg/day."
