Don't misunderstand what I'm saying about changing your lifestyle @Keith. What I meant is learning what to do with all that time you spent smoking. You now have to fill those hours each day with something productive rather than just going for a smoke. That requires some degree of change in your daily lifestyle.
Also, dealing with seasonal and other smoking triggers you may not expect after being quit for a while. I quit in late January and yet in mid April, the first lawn cutting of the year, I got acraving for a smoke because that was my reward for having finished cutting the grass in years past. I found it interesting how some of these trivial things in our life were wired to having a smoke, at least in our brain. It takes time to get through all that but it's certainly doable, especially after the early quit withdrawal is pretty much over.
