i'm on topamax and it works great for me. i take 25mg twice daily. i started at 25mg a day for a week then went up to twice a day, or something like that. i had previously been on neurontin, but it was making me sick, so my pm switched me to topamax, which i have no complaints about. it did make me a little dizzy/drowsy when i first started, but i'm over that now. i'd say go for it, give it at least 2 weeks or so, because i'm sure they'll have you gradually increase your dose, before you judge it, as you should all your new meds. goodluck!
