I have seen people have some success with these drugs for reducing pain in FM. Anybody tried both or either? They are both anti seizure meds. I have heard the topamax causes weight loss which would be a great side effect for me. But I am afraid that anything that causes weight loss will cause more insomnia, which is something I REALLY could not tolerate. I am going to ask my doc about these two meds, and just wanted any feedback from those using them.
