I just recently started taking Topamax for Fibromyalgia. After taking a different medication for a year and a half and the other medication stopping working, I was ready to try something else. When my doctor suggested Topamax, I was open to anything at that moment, especially when the only side effect she told me was weightloss and *other* medication I was on previously was weightgain. So needless to say I was happy to try to it. Not till being on it for a few days did I find out about the tingling in my fingers and toes and the very ODD taste it gave to carbonated beverages, I thought I was losing my mind when all kinds of sodas were tasting like metal. Now I can see where the weightloss is going to come from. I guess I can look at it as a positive, after 40 years, I will no longer be drinking soda. Just as long as I can get past the other side effects since I have only been on it a few weeks. The pain is gone though so that is a PLUS!
