Good luck with the weekend!
My first weekends sober became "date nights" with myself. I'd pick out a movie at the cinema, drive there, have dinner and a movie....and then the biggest luxury of all, drive home sober.
Your mind is going to try to play all sorts of tricks on you in order to keep the addiction going. When you have a plan, you start to feel a sense of responsibility to yourself to stick to not drinking.
Best wishes for the weekend. You can do it,
