my husband quit by turning off the cravings. he would drink grapefruit juiceto help clense his system. he would eat sunflower seeds to mimic the had to mouth motion. he would brush his teeth right after eating then use cinnamon mouth wash to clense his palet and made sure all cigs lighters ashtrays and such were out of the house and the car cleanned to avoid the smell temptation.

give it a try if you really want to quit
