I gave up when we bought a second house for our daughter to live in. The critical injury insurance premiums were so much lower for a non smoker. That was just the incentive I needed. Plus my friends wallets improved too.I use to smoke Rothmans roughly 20 day and my wife gave me incentive to stop by saving all money spent on cigarettes to buy a new car .....and it worked and it now been thirty six years since then .
