Just seen your thread voulez-vous (voulez vous quoi? if i can ask...) and I must say good on you to get this far and as you've got this far you're well on the way of fighting this battle. Remember, one hurts. Do not give yourself an excuse for having one no matter what it can be. When it comes to the crunch go and brush your teeth, this occupies your hand and mouth and you won't feel like taking that lovely fresh feeling away. Once I was able to get rid of the urge it was like floating on a cloud over the snow capped mountains, the air so clear... Keep it up, you'll never regret it and you'll say in a couple of years it was (one of ) the best thing(s) you did in your life.
