i believe 50 mg is a normal dose of topamax for most people. i take 400 but i started it on my own taking my sisters and was taking that dose when i asked my doc for it and that works for me. when i started it when i first lost my mind 50 didnt work for me. but my friends mom, who as far as i am concerned has worse bipolar than me, does just fine on 50 so it just depends on the person.

but i went from rapid cycling with some psychosis to nearly completely stable. i would have maybe two hypomanias a year. and as i said, my friends mom is doing great on it.
