You don't let situations "sneak up on you" until you've been quit for awhile.
Remember how we used to consider where we would be able to smoke in a new situation? You to turn that around and consider what might happen in a situation that would influence you to smoke. If your resolve is yet not solid, you avoid those situations for awhile.
Living free takes a little sacrifice but, not as much as you fear.
This is gradual
Life is just as much fun as a non smoker. Smoking was a lie.
The reason people thought smokers were more fun loving is because they had smoking in common. Addicts hang together to excuse one another.
