Much like
Gardner's multiple intelligences, I think there may be multiple wisdom modes as well. Therefore, I would volunteer to stand up and call you wise.
The whole quitting smoking thing taught me much about how the brain works in relation to habitualization. My wife (saint that she is) works in the psych ward at a local hospital here, and tells me tales of people coming off opiates and other drugs, including alcohol.
Anyone who has any time away from their addiction can feel good about it, but as you say, being forgiving of relapse is a wise course. Indeed being forgiving of human behaviors at all is one of the foundations of wisdom.
I know I have mentioned this before, but there exists a certain ghost like quality in any addiction. In ones "peripheral vision" so to speak, the cravings can be maddening, but seen straight on, they tend to dissipate like morning mist.
