I just thought of one more thing. The day after a holiday can be awkward. Sometimes when contemplating an event is going to be rough you bring up a high level of resolve and focus to survive the situation. Once it passes then, you may go to bed relieved that it is finally over, confident that now it will be a breeze. As soon as you feel this sense of relief, you are a prime candidate for the following though process. "Boy, I am glad that is over. That was really tough, but I made it and now on the other side where it will now be easy. I did a great job. Boy do I deserve a cigarette for that!"
It really can happen this way. As soon as you feel it should be easy you can drop your guard. Do appreciate the fact that you did get through a time period, but always understand that moments can still occur and be prepared for them. And no matter what you do, you never deserve a cigarette for anything. A cigarette is not reward but rather a punishment of suicidal proportions. Remember this always and never take another puff!
