get outside and go for a walk. Think about being sober and how much better you felt. I would NOT go and get sushi if it means beer and wine go with it. I would stay in and do something else, any activity that will take up your time.
Tomorrow AM (or this afternoon), you might consider getting an appointment with your primary physician and tell them the truth about your drinking, they will most likely help you detox at home and run some blood work so you can see where your liver enzymes are at.
