Does anyone have the shakes? I take Latuda, perphenazine and antivan. I don't know if it's my meds or anxiety causing it. My pdoc is prescribing cogentin to offset the trembles. Sometimes I feel like I have Parkinson's disease. It's awful to think that but I don't know how else to describe it. It's hard to cook, wash dishes, etc.... I need help calming down, any thoughts?
