I have been on Topamax for four months for epilepsy and I love it. I do experience some of the above mentioned side effects but my seizures were not grand mal seizures they were absence seizures. so the memory loss thing is a non issue for me, as far as depression, didn't get that one, weight loss; glad to have it, tingling; not that bad; the coldness; really only bothersome at bedtime so I take a bath at night, a really hot bath. Confusion, I was confused a lot because of the seizures so, again don't know which is worse. For me I feel this is a miracle drug. I'm not sure about the abdominal issues that is my only concern right now, that is what I am dealing with constipation and maybe some menstrual issues??
