Sounds like you're an alcoholic! The notion of just one drink is laughable. The notion of 2 drinks is laughable. The notion of 3,4,5,6,7,8,9 is laughable. You get the picture! LOL.
With me and drinking it used to be "I ain't leaving till I'm Heaving" Didn't plan on it being that way it's just I couldn't physically not stop drinking. The only time I would feel easy about leaving a pub/club or whatever is when I knew I had more cans and drugs waiting back at home, then I used to get positivley excited about leaving! Got to the stage where I couldn't be arsed to bother going out as it's easier to just be your own DJ and have your drink and drugs ready to hand... Glad to be out of that crazyness now.
