I dont think your problems are a side effect of gear, sounds like TMJ to me. i would go to the dentist and get a night gaurd, they are about $400 but you will sleep better and not grind away your teeth.
Now that I think about it. I have had grindig problems before. It's just gotten real bad though. It kind of confuses me because I have always felt as I was a stress free person and have been looked at that way from others.
