I don't have any advice, but I can sympathize, empathize, and send out great big cyber (((hugs))).
I've dealt with TMJ for many years myself, and had the worst bout I've ever had last Christmas. It was miserable and lasted a couple of weeks. Ugghh.
I'm glad you are better now. Soup and ice cream can get kinda old. I got to the point I was eating spaghetti sauce as a meal just for something different.
