What can I do to stop my hands and body from shaking. Would Cogentin help? I am currently taking 450 mg. of lithium carb ER Tab. I also can't sleep at night. I'm only getting about 3 hours of sleep a night. What should I do. I can't see my doctor until June 19. He is totally booked. I also am very sweaty all the time. I need some help with this problem I am having. I cut my legs really bad shaving the other day from my hands shaking. Please help me.
