Le Blanc

So I stopped last night and felt mentally good. I was laughing in the shower this morning as I would usually have smoked 3 or more ciggies before I bathed. Then I found a half a ciggie in the ashtray of my car and smoked it. Am I never to be free? I know people say that they have to battle cravings but mine are continual, they do not go away for days. Always in the background trying to 'negotiate' with me to smoke just one but I know that isnt true. How did you deal with this?
