Your isolation zone should lack your normal comforts and sensory input. It's a spot only for smoking addiction cigarettes. Addiction cigarette smoking zone. Isolation does not mean having a cigarette on the back porch with a nice view, sounds of the birds chirping, and a fragrant spring breeze. Being alone in a stimulating environment is not isolation.
Isolation is boring, bland, and quiet.
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.
