The first week is very hard.
Decide right now that you are not going to drink and picking up a bottle won't even be an option. Your AV isn't going to like it one bit and will scream and kick, but only for as long as it thinks it has a chance. You have to starve it out every time it kicks up , but it will weaken, I found it the stringest when it felt the most threatened when I was really garnering my resolve. Its hard , it sucks realize that and it will actually get better. You just have to ride it out.
wish you well
