yep - kidney stones and headaches and hair loss and don't take it if family history of closed-angle glaucoma. All well known and well-proven. The question is: is it worth it to you once you try it? I've used it for bipolar and it works. the bad news for me was hair falling out in clumps! sooooo embarassing during work meetings!! not to mention traumatic for my plumbing. But it has knocked down my pain from fibromyalgia a couple of points which was a totally unexpected side effect. I never would have known this if I hadn't held my breath and tried it, despite the very scary warnings.
