That is a good idea. Monitoring your symptoms by day and time is often helpful for spotting a pattern. Morning stiffness is common in PD, but it is important to let your doctor know. It could be that a change in medication may help.

If you have not yet been referred for physical therapy, I recommend that you request a referral. There is a specific physical therapy program called Big and Loud. It trains the patient with PD in both movement and voice. Do you currently have any speech problems?
