You need to make lots of good decisions when you quit smoking to keep it your #1 priority. One of the most important is whether to continue going out on the weekends with friends or family and including alcohol. This is another area of your life that it is important to change a bit, especially early in your quit. That one bad decision to drink has caused a LOT of quits to be lost by members of our community. I have read about it over and over through the years, and don't want it to happen to you. Do you REALLY know how much alcohol it takes for your addled brain to believe "just one won't hurt?"
A quit is a terrible thing to lose.
