I Have Problems that are the opposite of what you described. When I come down from my drugs I have fo watch out that I don't drool, and if I'm eating something I sometimes chew the inside of my sheeks. lf I let myself get that low I have to lay down for 30 to 45 minutes in order to recover.
the only good thing I have going for me with that condition (frozen facial features)) is that it makes for a good poker face. So see there is aways a silver lining if you look for it

It's my understanding that jaw clenching is very common. Clenching and chattering teeth is the first indication that my meds are wearing off. I currently take 2 Sinemet pills every four hours. The chattering begins about 1 hr. before the next dose is due and continues for about 1 hr. after taking the pills. .

Yes it is a problem I do constantly. I cracked my denture and have cracked two teeth which now need to be pulled. It is only since my PD was confirmed. The chattering and clenching is a real nuisance. Grace and Peace to everyone.

Teeth clenching is part of my dyskensia. I had more dyskensia when I was taking Rytary exclusively. That's one of the reasons I backed off the Rytary and added back the immediate release Sinimet.

Thanks for the info mate I never thought of that correlation between the time of meds to the chattering I will keep an eye out for that. Thanks again God Richly Bless you and your Family mate
