I am puzzled by the lack of discussion on this subject. It's my impression that one does not have symptoms of Parkinsons while asleep. Is there a neurological switch that gets turned off? Maybe it just turns off parts of the system. I drool by day, mostly because I forget to swallow. I drool just a relatively tiny amount at night because I fall asleep before I make a big puddle, and I swallow from then until I awake. I gasp for breath when I'm "off" by day - even when I'm trying to get to sleep. Once the switch is thrown I breathe with rythm. What goes on here? My arm is shaking like a vibrator is attached to it as I pull up the covers to go to sleep, All is calm and quiet a few moments later when I'm asleep. Not that it's easy to get to sleep. I prowl the house, try different chairs, unoccupied beds, make something to eat, read. But once I'm asleep the Parky demon is gone. Can someone explain? Maybe this is a back door entrance to solving the mystery of Parkinso
