I have had trouble sleeping. Would go to sleep and then wake up about 2 and be wide awake all night. After talking to my health food shop (the owner had pd for 20yrs.) I started taking CBD. 12 drops under the tongue before going to bed. I now sleep great and rested the next morning. It seems to really help pd and I have read that it could be neuro protective. I take CBD Gold with turmeric. I also take mucuna one or two per day this may help also . Hope this helps someone.
