Topamax saved my life. Comes down to everyone reacts differently to each drug. I started slowly, on 50 mg, and worked myself up to 300 mg a day to prevent seizures. It worked the miracle, stopping the seizures and giving me a life back. I lost 45 lbs, I'm at a healthy weight now and sustaining it. Side effects: math skills are laughable, tingles in hand, vocabulary comes and goes. These diminished somewhat as I adjusted to dosage. Side effects are a small price to pay for the desirable primary effects. (I bought a calculator and a thesaurus.) Life is good. Topamax is damn expensive and worth every penny.
