I am taking about 100mg of topamax in the morning and 100 at night. The side effects I receive are dry mouth, speech impediment, and a definite decrease in appitite (which I like though) . But I am also on lamictal and that also contributes to the decrease in appitite. But again if these side effects are not making you comfortable, why make your life miserable. I was on trileptal and every morning I was on that, I felt extremely dizzy and light headed at work and I felt like I was going to fall alseep for about an hour. So I made my Dr. take me off of it. No need to feel like that. You go from taking one medication to help seizures to another medication to fix the side effects of that other medication. Makes no sense Hopes this help.
