If you are new to your quit,and even if you are further along, it's a good idea to start planning what you will do when faced with a choice whether to drink alcohol.
We know I will recommend against it - because you really don't know for sure your personal threshold (the point at which smoking "just one" seems OK). If you must, limit yourself to a celebratory glass of champagne to welcome in the new year - and keep it at that one.
Why take a chance? A quit is a terrible thing to lose!
