Another way to get around waitlists for treatment centers is to try Rational Recovery. It is an alternative to AA that believes recovery can be achieved by becoming aware and listening to our self-talk (the Beast).
Rational Recovery does not depend on other people, instead you are encouraged to cure yourself without the help of other people like a sponsor. All you have to do is visit the website and take the crash course on the Addictive Voice Recognition Technique (AVRT). The founder of Rational Recovery claims that you can quit now and forever. Give it a try if substances are negatively affecting your life.
