About 30% of alcoholics are able to abstain from alcohol permanently without the help of formal treatment or a self-help program. For the rest, the course of the illness is very varied. Some people will go through periods where they remain sober, but then relapse. Others have a hard time sustaining any period of sobriety.
It is clear, however, that the more sober days you have, the greater the chance that you will remain sober. Another motivating fact – remaining sober can increase life expectancy by 15 or more years.
