Those of you taking Topamax, you may want to talk to your doctors about trying Zonegran. I took Topamax for "dizzy migraines" and although it worked I had the same side effects you are all mentioning. Although the Zonegran did make me sleepy, if I took it at night I was at least able to function the next day plus no tingling hands or feet which on Topamax was a nightmare. If you decide to stay on Topamax know that Vitamin C helps with the tingling hands and feet very much (my neurologist told me this) and it truly works!
