Find constructive, non-drinking ways to occupy your time. Find a hobby, volunteer your time, read a lot, get into physical activity .... anything that gets you out of your head and into life. Diversions are incredibly useful during those first early weeks. "Down time", i.e. boredom, were killers for me. Keep a journal, do a gratitude list, get out of yourself for a few hours a day. Eat. Doesn't matter if it's healthy or not, EAT. Stay hydrated. Take vitamins. Come to SR. Read recovery books. Make a list of the things you did while drunk that damaged you and others. Then make a list of the crummy things you felt physically and mentally while you were drinking. Write down the details of your last drunk and post them on your fridge. Make sure you eat when you're hungry, get lots of fluids, and sleep when you can.
