After reading these horrific side effects, I am not alone. I have only began taking topamax 25 mgs once a day and then I am suppose to increase it to 200 mgs. in a month which I am not sure I am ready to do that. I take it for migranes, I have had tingling in my feet and numbness in my hands, sleeplessness and loss of appetite. But I feel that I am getting better even though I am suppose to increase he dose next week, I am not so sure what I am going to do yet. Any siggestions?? I am going to call the doctor but then again it is not really his call , it is mine, do I want to live with the headaches? or can i stand the side effects until my body gets use to the medication?
