I just discovered something that helps me to keep from biting the inside of my mouth. Cut 2 pieces out of the side of a one gallon plastic milk container, each about the size of an elongated quarter. Put a piece in each side of your mouth. Bingo! You can’t bite the inside of your mouth and you barely notice that it is there.. AND, you can still talk easily. Hope this works for you. I’m 71 years old and I have been fighting this for decades.
It is May 1, 2012 and I haven’t bitten my mouth in months, the longest success I have had in decades. This procedure has really helped me to overcome this bad habit. I hope others having this problem will try the procedure and let me know your results.
