I have been taking Topamax for almost five years. I am currently taking 200mg in the morning and 250mg at night. The tingling in my feet and hands come and go. The weight loss has tapered off. My neuro and I very slowly worked up to this level but it has finally put a halt to my migraines. I may have one once or twice a year. He says this is the highest we could ever go so thank goodness the headaches stopped. The past year I have begun to be very forgetful, Over the past three months it has started to affect me on a daily basis. Over the last week, I haven't been feeling like myself and have started to feel emotionally numb. Meeting with my neuro today, Not sure if its the meds or not causing me to feel numb or just life's' stress.
