I grind my teeth viciously every single night, gradually assuring myself not only a morning of powerful, thick headaches, but also a full, long life of dental work. I do this because I always internalize my continuous tension, and this internalization allows me to give off a mirage of a calm demeanor. I don't scream, don't explode in anger, don't punch walls, don't smash bottles.......all I do, when tense, is take it out on my poor teeth.
I've tried mouthpieces, to no avail. My mouth just fills up with saliva and I spend my first moment of the next morning just drinking a long night's worth of spit. The headaches are large in scope - a pounding, encompassing, skill splitting, yet dull pain.
I rarely bitch about this. After all, I'm a man, right? I had to think very hard about the answer to this "pain" question, because I tend to ignore my physical pain as much as possible. It's just not manly to talk about how much you hurt. While nobody likes to spend time with those constantly bringing up their injuries in conversation, it's probably nearly as unhealthy to internalize all pain.
