Why is cracking knuckles addicting?
Here is a good way to stop from cracking your knuckles, but I have to warn you it hurts! Get a large elastic band for each wrist. Wind it around until it’s just resting (not cutting off the circulation) and when you feel you are going to crack your knuckles take that suckah of an elastic band and stretch it and let it hit your wrist! After a week believe it or not you have tricked your subconscious “not to crack your knuckles!” One of my girlfriends stopped her nail biting by doing this.
