Comprehensive studies have established that relapse is the most common outcome of recovery programs treating addictive behaviors. This article examines the fact that relapse is often related to uncovering painful early childhood incest experiences that have been defended against through self-destructive addictive behaviors. Another aspect of relapse is the phenomenon of multiaddictions: withdrawal from an identified addictive behavior will often lead to the unmasking of other addictive behaviors. The phenomenon of cross-addiction is widely acknowledged in the addictions field, but the connection between cross-addiction and relapse needs to be more fully explored. This article focuses on the following points: (1) addictive behaviors may serve to defend against memories of sexual abuse; (2) unidentified incest material may precipitate relapse or result from relapse, and therefore must be considered as a possible component of treatment in recovery--indications for treatment in terms of 12-Step recovery in conjunction with therapy are explored; (3) relapse may indicate the existence of additional addictions that must be identified and explored in order for recovery to proceed; and (4) sex and love addiction is often found in conjunction with alcoholism, codependency and compulsive overeating, and often comes to light through the emergence of incest memories. The identification and treatment of this hidden addiction (i.e., sex and love addiction) will determine the extent and depth of recovery.
