Alcohol is a bitch. It feels good. It feels relaxing. The physiological effects are not all good.
Drink if you want to. Make sure you are aware of your motivations when you begin to fix the third cocktail. In my experience, that Third Glass came to represent a turning away from me and away from intimacy. I would choose to drink with her from time to time, but I could not follow her into the nightly oblivion. I wanted a close relationship.
