I went off Topamax for a while, and had decided it was not worth having migraines! (My insurance will only pay 50% of the price
of Imitrex or Maxalt, or any drug, and worse yet, limits me on how many a month, so I need a way to PREVENT migraines.)
The real reason I need to drop Topamax is due to the Brain Fog. I work for a major corporation, and have made a few public blunders like forgetting stuff, in the last year.
