Many say drinking lets out another you. I tend to think of it as a lesser you. Sober, humans possess many neccessary attributes that make them human. Drinking too much can easily switch these off, thereby rendering one "sub-human". Case in point: once I was awakened by my mother wondering why there was a half chewed up raw steak in the kitchen sink and blood all over the place. Then I remembered. It was not pretty at all. I know I was hungry, but Jesus.
