This will be a great help during early recovery. However, it’s no substitute for a program.  No “magic bullet” will undo the psychological and social damage done by addiction.  Only a concerted effort over time to straighten out our thinking and clean up the “wreckage of the past” will give us the self-image and confidence to pursue long-term sobriety.
