topamax side effects bipolar

Serious side effects of bipolar medications?
I've been taking BuSpar, Topamax and Cymbalta for a while. He was taken out of my Effexor, because throughout of my Cymbalta (which is my newest drug). In the last couple of weeks I've been feeling very dizzy while I lie down, and while sitting. Also in the last two months I had terrible headaches. Could my medications be causing this?
