What number of alcoholics can actually quit drinking and live a productive life?

Most of them IF: they get proper treatment. Recovery rates of alcoholics who enter treatment, in a number of large studies, approaches 60%. This may take more than one treatment episode, and there may be relapses, but about two thirds of alcoholic patients will attain long-term sobriety WITH TREATMENT. However, fewer than 20% (10% in some populations) ever seek or receive treatment.
