Wife and I bought a house with the agreement that we would not smoke inside. Then we stopped going out so much, argued a lot because quitting sucks and we did it at the same time. Eventually started going back out and have both been smoke free for a couple of decades.

It really took a lifestyle change to quit since the worst triggers were environmental, physical addiction was secondary.We also had tapered down a bit while house shopping and finalizing the sale so we had whittled down the number of cigarettes per day over time before stopping completely. The house was a nice reminder that we quit at first, and then a reinforcement during later temptations.
