So, topamax didn’t work because of the cognitive fogginess, so my dr. has me trying this. I have only been on it 4 day, although I’ve had it for a month but have been leary of starting another new med. It doesn’t seem to have the cognitive issues that topamax does. And so far I haven’t gotten the hives that seem to be the major side effect. My Dr said it will be several weeks before I see results if I’m going to see them. Just wondering if anyone else has tried it and what kind of results you have had?
