If I discover one of my cats has my bite guard, I am definitely going to have me a new hat come winter.
I tried a drugstore variety bite guard. It didn't fit well at all. I just have to continue to clean and de-clutter and hope it turns up. One good thing this is going is forcing me to really focus on ways of getting my shoulders, head and neck to relax.
I have discovered a Feldenkrais lesson designed to make breathing easier. It helps to relax chest and neck and head.
Acupressure is helpful as well.
For about a month, I have been following Dr. Ellie Phillips' program for strengthening and remineralizing teeth. She says that strong teeth are more resistant to the effects of clenching, so I'm hoping that will help me as well.
