Day grinder

When I was at the dentist the other day, the hygienist suggested I get a mouth-guard because she could see I grind my teeth. And I fully admit it. I am, as the dentist later said, a "grinder."

The thing is while I know I grind my teeth,  I am 100% sure night is not the problem.

I grind my teeth when I fell or when I bang my foot into my chair.

I grind my teeth when works goes poorly or when my computer fails.

I grind my teeth when I think about Friday when I have a scan to see if the nodules on my lungs are anything.

Night might be the one time my jaw relaxes.
