I have only been taking meds for 3 months, Sinemet x 3 low dose. Worked wonders for lifting my energy level, removing anxiety and helping with rigidity and had no more freezing. Now neurologist feels I could benefit from adding Half Sinemet CR at night to help with minor tremor (whole of right hand side), poor sleep pattern, and morning stiffness. I am reluctant to increase meds at this stage. Has anyone experience of taking half Sinemet CR at night for these symptoms? Any help? Any side effects?
