What you nurture will grow. If you attend to thoughts about drinking, you'll have more thoughts, and more, and they will seem powerful and compelling because they'll dominate your mental space. If you attend to other thoughts -- thoughts about how much better you'll still look at the end of the evening, and how much better your breath will smell if you're not drinking, and how you'll be able to wake up the next morning with your husband without wincing from a hangover so you can not only have a date night but a date morning.... sounds like you can create a really special occasion! Have a great time
