Hello @kinglue, and welcome to the PD support group on Mayo Connect. I'm sorry to hear that you experience headaches as you increase your dose of C/L. Before you increased the dosage, did you notice any improvements in your PD symptoms?

As this is your first post, please share, as you are comfortable doing so, a bit about your journey with PD. Is this a new diagnosis for you? What symptoms led to the diagnosis? Have you asked your doctor for a different PD medication?
