How funny-I just popped in here and said that I overcame this habit. Underneath my name it says “Worth doing!” Guess what-I’m chewing right now and have been for about a week and a half. What happened was I accidentally bit the inside of my mouth really hard and that left a sort of (sorry, TMI) flap of skin just hanging there. That’s like offering a drink to a former alcoholic. I started chewing it just to smooth it out, but I found that every day I was doing it more. Right now I’m at a point where I’m chewing just as much as I used to expect, for now, it’s only on one side. I don’t know what to do-I just can’t stop. I keep waking up and saying, “Okay, no chewing today,” but then I go right back to it. This doesn’t mean anyone should give up-it can be done and I was doing very well for a long while, but bad habits come back fast. Be careful and good luck.
