This Relapse Prevention Therapy Workbook from www.relapse.org is designed for people in recovery from alcohol or other drug addiction who have a history of relapse, or are currently afraid they might relapse. There continues to be confusion and misunderstanding about what relapse is and how it happens. In this workbook, Terry Gorski and Steve Grinstead clarify their definition of relapse, how it happens, and most importantly how to prevent a person from entering the relapse cycle.
