Wow … I knew I wasn’t alone but I never thought this would be on 43Things! I’ve had this habit for as long as I can remember. I find it to be a figety habit – it isn’t a sign of OCD or anxiety disorders – that is no more weird than tapping your feet, just more destructive. The only thing I have found to help is chewing gum – it gives my mouth something to do but I still find myself chewing the inside of my mouth so this isn’t working too well. I’ve tried to make myself stop, but it is such a strong habit and one that is quite unconsciously done that I don’t know how to make myself stop.
