Use Sim Cigarette as a virtual placebo when you are trying to quit OR as a cigarette break timer. Burn rate is either manually controlled, or timer based.
Sim Cigarette is a nice application that was designed to provide you with a realistic substitute for smoking. You can light up a virtual cigarette and take the usual smoking break without leaving your workplace.
Research demonstrates that the brain cannot fully tell the difference between real and virtual experiences, and that simulated experiences can have physical affects. If you are trying to quit, Sim Cigarette is an ideal and inexpensive virtual placebo.
