If all other methods for getting rid of your addiction has failed, the Linkman may help you stamp out cigs for good—provided you follow its guidance.
Whenever you feel the urge to smoke, double click the button on the Linkman. If the light turns green, go ahead. If it's red, you need to wait. The Linkman starts its minimum wait-time at 10 minutes, then gradually increases the time every time you press that button. Eventually you'll reduce your cigarette intake to something more manageable—or possibly even quit entirely. If you don't quit for your kids, quit for the guy (me) who has to smell your smoke.
