It definitely helps to have a plan.
I'm not one for meetings either (have tried them in the past and they weren't too helpful) but I'm about to start a yoga class and have been doing meditation and some things along those lines. Anything stress relieving where I know I won't run into people drinking.
Lots of long walks - thankfully my neighborhood has a beautiful bike path through the whole city I can use.
Those sorts of things have been helping me a lot so far just to keep me busy and keep my mind off of drinking.
Also, especially if you're in entertainment (I am too- lots of drinks around,) it's good to have a plan for what you're going to do when you're out and offered a drink or around others that are drinking. Have a game plan for that is a good place to start!
