Avrt
Science isn't required. Excessive drinking is not a disease, so scientific/therapeutic approaches aren't required.
AVRT is a decision-making process taught via a series of lessons and written material. The material teaches people to separate their urges from their bodies.
You don't smash the pie case in the grocery store when you are hungry. You don't act on sudden sexual urges in public. Drinking is no more than a similar bodily urge. AVRT teaches people to recognize that.
The lessons teach a form of self-talk that is useful in responding to the urge to drink. That urge is called the "addictive voice." It is housed in the primal brain, termed "the Beast."
The Beast is dumb and easily silenced with the self-talk and decision making process taught by RR.
If you object to the lower brain being called Beast, that is a sign that you don't recognize the immorality of your drinking.
Yes, immorality. RR teaches that recovery is a self-help effort, alone. That drinking to excess is immoral, not a disease and not because your mommy didn't love you enough or because they teased you too much in junior high.
The lesson plans and decision making process easily lead people to realize the immorality of their continued drunkeness. But it isn't for people who don't believe in self help, who want to involve strangers in their drama or who can't face the truth about themselves without a lot of excuse making and panel discussion.
