Just wondering how long you've been doing this? It could just be a habit that you have become so accustomed to that you now do it subconsciously!

I bite my cheek....and when I discover I'm doing it...it annoys me and I stop. Been doing it for as long as I can remember.

I think it has something to do with my lack of patience. Your leg fidget could have something to do with patience or the lack thereof too! It's a way for me to be doing something.....ANYTHING....other than saying...."Hurry up, damn it"....whatever the circumstance is. Playing cards is an especially nerve wracking time for me!

Just a thought!

*bites my cheek while waiting for an answer*....LOL!
