@rashida, @lcr I had the very same experience as you, @rashida, regarding chewing gum! I was almost addicted to it at one short period when I used it to alleviate stress. Chewing gum really seemed to help. I finally had to STOP, due to constantly having those awful, and painful, incidents of accidently biting my tongue or inner cheek. It was a very difficult habit to break at the time too, because of ongoing anxiety I was experiencing. I'd been fitted with an expensive oral appliance by my dentist, but I've forsaken it because it's very ill- fitting. No refund of the $500 by the dentist either! I've had other oral appliances over the years that worked quite well though, so @lcr, please don't hesitate to give it a try. I wore it during quiet alone times and at night for relief of TMJ and bruxism. No drooling either! Lol. And if you're alone, who really cares?
Good luck! Laurie
