Addiction treatment facilities founded upon a recovery oriented system will also have things in place to help you with long-term plans for staying clean and sober.
Long term plans will often involve the 12-step program and fellowships like Alcoholics Anonymous. Treatment is often seen as the beginning of recovery, support groups like Alcoholics Anonymous can help you with the following steps of the journey. It can also involve going to regular meetings (outside of treatment) and even working with a sponsor.
Goal: Get what you can out of this while in treatment. If you are accustomed to going to meetings and working the steps when treatment completes, you are more likely to keep up with the practice after you leave the care of the facility.
