Iknow it seems silly at first, but I think it makes a huge difference in my neck, shoulder and chest muscles. I was away the weekend, and didn't chew - felt better, looser. Came back, and went back to my teaching job. I'm going a million miles an hour and am addicted to it in that situation. I was joking that I might take up smoking. Get it? the opposite of what most people do. Any suggestions? I know it's a nervous habit. Hugs to all.
