Wow, sad...I grind my teeth too, and I have serious muscle spasms, incapacitating sometimes.
I think the reason I broke my 1800 dollar(out of pocket with insurance) new bridge in my teeth, for which I have had to go back 3 times to have the section glued back in until the new one is made, is teeth grinding. My ex would tell me I ground (?) my teeth so loud in my sleep, if I tried to duplicate it while awake I would stop before it was even close to what I did in my sleep (as he told me) because I was afraid to break my teeth!
It's been a rough week.
Miller Lite isn't the worst medication.
