I stopped taking my topamax 2 weeks ago, if I start taking it again, will I lose weight like I did the first time I started taking it?

The amount of time it took the first time will be the amount it takes to see the affects this time if you start back up, bearing you didnt change your eating or exercise habbits drastically.

You should never stop taking Topamax without first checking with your doc. Call your doc and let him know that you are not taking it and ask him about restarting this med. As for weight loss there is no way of telling if you will have this side effect or not.
