I do this in my head (day 22 here), and always admonish myself for it, but it's almost a reflex. Sunny day, let's have drinks. Stressful day at work, wow - drinks would be an awesome release, and on and on. Then I catch myself, and go, "Oh yeah, I don't drink anymore!"
The lack of hangovers on the weekends, just the physical part of it, has already changed my life immeasurably. I also do not actively hate myself anymore.
