My impetus to quit smoking was my 5 yr. old son pestering me about why I had such an unhealthy, smelly habit. So I told everyone around me that I was quitting and would be a miserable sob for awhile. I went cold turkey and had a difficult time wanting a smoke with coffee, stress, post-sex, booze, social events, etc, for about 6 mos. Then I became intolerant of smoking smells and a happy camper. I see no sense in substituting one unhealthy addiction for another, like vaping.
