Fancy!! This is just one night in your life. Do not give up hope. Stop drinking, get some water, take a walk, wake up tomorrow and hop right back on the ride. What's done is done, you can't "undrink" what you drank, so there's no reason to get yourself down over it! You don't lose the battle when you drink one night, you lose the battle when you give up! You've been there for me and you can see how much trouble I'm having also with this and you can read other threads about how much trouble it is for a lot of people. You are not alone. You just gotta keep on fighting.
