Will you drink yourself to oblivion and lose your quit?
Christmas can be a very negatively emotionally charged time.
Memories are dredged up and interaction can be uncomfortable as a result.
You may be tempted to drink too much.
If you drink too much you will most likely be tempted to smoke.
Where will your quit stand among all this?
You may as well decide right now if you're going to smoke or not.
Why wait until you are too drunk to care?
