who told you topamax was an ad? it isn't. It is used as a mood stabilizer. That is what I am on besides antidepressant. But it has been found to help migraines and food disorders and possibly alcholism. A possible side effect is weight loss. I had some cognitive difficulties when I was on 200 m but now I am on 100 and my memory hasn't been sharper in years besides all this depression and anxiety and irritability and lack of sleep.
