I've been on Topomax for 5 months and I've had the usual side effects (weight loss, memory issues, tingling). I'm currently on 100mg 2x a day. Recently I stopped sweating and my doctor has run every test she could think of to find out why. The only thing she found was that I was diabetic. I go to an endocrinologist next month for the sweating issue. When this first happened I looked up Topomax to check the side effects to make sure decreased sweating wasn't one of them. I didn't find it listed anywhere. I did another search tonight and found that decreased sweating is a side effect. Has anyone experienced this and what did your doctor recommend? Thank you for your help.
