I don't understand this. If you've been dry for a week, why can't you control your cravings some other way? You're not going to die. You know what happens if you drink. SO JUST DON'T DRINK. It's not rocket science. Find other things to do. Get a therapist. Go to meetings. Rehab isn't some magical cure.
You're halfway out of the woods, past physical withdrawal. Do you know how lucky you are! Just. Don't. Drink.
See my signature? Say that out loud 100x a day every day until it sticks.
Sorry for being kind of a jerk about it, but I just don't understand why you feel you need to be locked away. There will always be bars and liquor stores. They'll be there when you get out of rehab. The problem is not outside in the world, it's in you.
