I do agree...hurts like HELL! I have TMJ--I grind my teeth at night, in my sleep. Needless to say, more often than not, I wake up with excruciating pain in my jaw, teeth, & gums.
I've never had a problem with drinking, but I know a few who have (family members, an ex of mine, etc.). Rehab does work IF you stick to it. If you can't pay for it, there are programs to help assist you, I'm sure.
I wish you all the best, and you should feel proud that you are taking a step in the right direction to get some help for yourself!
