There is another thread going on here now that's talking about topomax.....& made a comment that Dr's call it DOPAMAX.....because of the stupids it leaves you with.....all in all, I think I'm glad they never tried that on my migraines even if it would work.....who would think that the high dose of Fentynal that I'm on doesn't have any side effects & I have been more alery & aware than I was for a long time.
