I have been on Topamax for 7 years 100mg TID. I recently (last 6 month- 12 months have had increased weight, increased heart burn, and increasing headaches) I cannot take tricyclics and beta blockers don't help. Any insights would be welcomed..tired of being in pain. Topamax was originally a wonder drug for my Migraines and trigeminal neuralgia that I have suffered with for years feel like I am back to square one.
