My comments below are based on my own experience, and observations from watching people that succeed and others who fail at staying sober through the program of Alcoholics Anonymous…a group which I realize is not held in high regard my many. It does have an advantage over expensive treatment programs in that you need not be wealthy to keep trying it until it works, and it is not uncommon for a drunk to need several swings at the ball before connecting.
This. When you get to define “cure” then your success rate can be very high. If an alcoholic has not done major damage to internal organs, then they will start feeling pretty healthy around 2-3 months dry, and memories of hangovers and blackouts start to mellow with age, and sleep patterns start to normalize. It is not uncommon for them to decide that they are now cured, and can therefore safely drink in moderation. This seldom, if ever, works out well, because by the time treatment is sought, an alcoholic will usually have lost all ability to limit his consumption, and no, there doesn’t seem to be a way to restore that ability.
Even if they don’t decide they are “cured,” many will end up drinking again if they maintain their old habits and ways of thinking and dealing with others. Many, probably most, alcoholics drink to escape unpleasant emotions. Without tools other than alcohol to deal with shame, resentment, fear, anger, etc. it is only a matter of time before the dry alcoholic picks up a bottle again. Long term sobriety depends on acquiring sufficient skills to deal with life’s ups and downs without needing to escape into drunken oblivion. These skills will not typically be learned well enough to stay sober in less than a many months at least, and often well over a year, and then honed through maintenance and practice throughout life.
Without such skills, the dry alcoholic is frequently, as they say in AA, restless, irritable, and discontent. Some of strong will can maintain such a state for months or even more than a year, but they will not be pleasant company most of that time. The trick is for the alcoholic to learn to enjoy his life without alcohol. That done, staying sober is no feat at all.
If the program in question allows people to live a pleasant life, and still be dry after a couple of years, then I’d say it is successful. If success is measured as days or even a few months without drink, then I can recommend a number of cheap and even free ways to do that. Here’s one: “Just don’t drink.” I know at least a dozen alcoholics (one is me) who made that one work for a month or three.
