Don't drink no matter what.
I had to promise myself things like "ok, I will not drink for the next hour."
Change the people, places, and things in your life because your life and your freedom are at stake.
Don't go to places where there is alcohol - a bar, a friends' house, even the grocery store.
Avoid people you used to drink with. Go to AA or SMART or SOS or any other recovery group/meeting instead. Find sober people to be around.
Trash your stash. Get rid of every drop of alcohol in your house. Even cough syrup and mouthwash. Do not allow anyone else in your house to bring alcohol in.
