No alcohol with your quit
You might lose it, then
You can only say "Oh, d@mn!"
This site is littered with tales of folks who drank alcohol and thought just one would be fine. It NEVER is going to be just one when you are an addict. It will always, maybe not right away but always, lead to another and another until you are a full-blown smoker again. It's the nature of this addiction.
Please don't chance it this weekend as you unwind. A quit is a terrible thing to lose.
