When someone wants to join a 12-step fellowship for alcoholism, they join AA (Alcoholics Anonymous).
When they want to join a program to help with various drug addictions, they join NA (Narcotics Anonymous).
When they want to join a program to help with eating disorders, they join OA (Overeaters Anonymous).
When they want to join a program to help with sex addiction, they join SA (Sexaholics Anonymous). Or do they join SCA (Sexual Compulsives Anonymous)? Or do they join SLAA (Sex and Love Addicts Anonymous)? Or do they join SAA (Sex Addicts Anonymous)? Maybe they join more than one. Maybe they attend open AA meetings instead. Maybe they join a Christian program like Celebrate Recovery which combines the teachings of the Bible with the steps and principles of AA to work on all addictive behavior (N.b.: This is a non-denominational program founded by a Protestant pastor, John Baker, of Saddleback Church).
