Yeah, when I get the urge to grind, my jaw tightens so much it starts to hurt and sometimes I end up subconsciously giving in sometimes I just subconsciously clench my jaw. I try to do other things to distract myself while I'm awake...but my gum chewing habits also get so bad my jaw starts to hurt. Hopefully you can find a way to beat this or you'll probably have to sleep with a mouth guard or something. Good luck! For me, I notice I feel the urge to grind more when I'm stressed or when it's brought up. Haha, you don't know how much I wanna just do it right now, Haha. I sometimes chatter my teeth to get over a huge urge, lol. Only when I'm alone.

Put them in a blender and drink them!

Damn you'd think the brain that controls your jaw and the brain that controls your tongue were like, not the same one or something.
