My nerologist put me on seminet (a parkinsens Med) for my RLS. I have since spiraled into this never ending rapid cycling state. Within hours I am manic to depressed and back again. There is no middle. My pdoc said this med would not cause this to happed, but I don't know if I believe that. Any comments if anyone else had this problem. It could have been the lack of sleep from the restless leg syndrome that just finally took affect.
