I have jaw tremors too, although they haven't as yet affected my eating

l I have swallowing issues a nd reflux so i can emphasize with your
frustration.
The only thing I can think of is that when I have jaw t r emots and cáuse
me to grind my teetht,, iv use a mouthpiece, you can get at Walmart or
target, are any drugstore for about $20. This calms my tremors so , i can
sleep. You can't eat with it on but if you put it on for a while before you
eat for a while before you eat, Maybe your tremors will have calmed down
enougĥ to eat. Hope this helps.

I have problems swallowing and choking. I have to remember to chew my food really well. Just another charming Parkinson’s side effect.

I do Kathleen, that why ai lost 27 lbs &!have Parkinson’s induced gastroparesis.

Carbidopa / Levodopa

I hope this goes away. Do you take anything for your tremors like carb? – Levo?
I hope it gets better for you.
