I'm thinking at around 5 years quit, you really begin to hit your stride.
You don't think of smoking but rarely, and it's more like a loose memory than urge to smoke.
Remember the red hot poker plant I posted about a couple months ago?
That plant had never shown more than 2 blooms at one time until this year.
I thought it was done blooming weeks ago but just look at it today.
I think it finally hit it's stride this year.
You'll hit your stride too in time.
Become comfortable in your quit. Only you who can allow that to happen,
and, why would you choose it to be any other way?
