Priest LeviathanXIII has it absolutely right in my opinion.

"Recovering" is the term used by the venerable 12-Step Program of Alcoholics Anonymous and Narcotics Anonymous, etc.

They wish to assume that drinking or drug abuse is a "disease" and that there is no "cure".

Proactive approaches based on using one's willpower (such as Rational Recovery) have a demonstrated track record of success whereas the AA approaches seem to have none at all that is worth bothering with.

You quit drinking and it was a problem for you?

Good for you!

You get the full credit and the rewards that come with knowing how to deal with that issue.

You are not "diseased" or "incurable".

You are willful and wise.
