At 50mg a day, Topamax, taken at night, makes me feel very heavy, tired and numb all day. I have been on it for 3 months so far. I also have other side effects mentioned in previous posts. I hate feeling tingly in hands and legs (from the knee down) and sometimes in my face. It is supposed to go away - soon? I get a bad case of my legs falling asleep in almost any position I sit in other than total upright (which is not comfortable). My lifr-long instiable appetite is hardly affected. I'd say maybe a little bit. I do notice taste difference in drinks and food, sometimes more than other times. I need this medicine for Migraines, it has help relieve my symptoms, but I think I need to continue to increase the dose because I still get Migraines and feel pressure in my head a lot.
