I was on Topomax for years for migraines. It is an anti-epileptic drug that is used for a variety of things. Certain Types of seizures, Migraines, bi-polar disorder, weight management, and i've heard they've useded it for alocoholics trying to quit drinking. You have to ween yourself on and off of it VERY slowly. Your dr's advise sounds too quick to me. you should be on each 25 mg. step for at least a week before increasing it. I lost about 20 lbs when i was on it, but have gained it back. There are A LOT of side effects involved with this drug, so make sure you really do your research on it. Weigh the pro's and con's of this drug. if you are on it for weight loss, this isnt a permanent solution. good luck.
