This is exactly how I quit, and also almost 42 years ago (1979). I moved to Vantage, Decade, Carleton, and Now, I think (not sure of the order anymore). One day I realized I hadn’t smoked all day, and just stopped. Pretty pain-free. But I’d only smoked 1 pack a day, so I had an easier challenge than someone smoking 2-3 packs/day.
