I have been taking Topamax for 3 years. I started out at 25 mg, ramped up slowly to 75 mg and have been on 100 mg for 1 year. Over the past 2-3 months, though, I've been feeling very weird, almost like I'm not here sometimes. It's hard to explain. Sometimes I'll get all the way to work and I can't even remember getting ready for work. My short term memory is shot, and that's bad for me. I used to remember everything. I just don't feel like me anymore. I did lose about 30 pounds when I started taking it, but I've gained that all back. I also had tingling and the carbonation in sodas went away for about 6 months. It did take away my headaches for the most part. Axert alleviates any that I do get now.
