The addiction smoking zone should isolate you from all positive sensory input. No hot radio tunes, no pretty people walking by. If the zone smells good, you'll need nose plugs. No day dreaming about your upcoming camping trip. Nothing but you and your addiction cigarette.
Isolation means finding a spot in the garage with a blank wall.
Stand about two feet from the wall and face the blank spot. Now smoke your addiction cigarette. Nothing else can be happening. The addiction cigarettes are not going to be that much fun, but remember, you don't have to give them up cold turkey. Anne's isolation was facing a wall in the corner of the basement.
