God - spirituality in healing addictions?

I was a monk for many years and have more recently been a specialist Director/Therapist in Rehabs and private practice. The wounds of addiction run so deep in the person that needs a deeper belief and spiritual practice to heal....So:

• They will have huge amounts of guilt over things they've done in active addiction!
  
• They will need to find strength from somewhere else to beat the cravings etc.
  
• They need to change themselves and live by new standards... contributing to their world. They need to learn to self-accept... spirituality aids this.
  

But, a 'real' spiritual discipline needs to be established in order to secure 'long-term recovery'... by 'real' I mean one that is challenging and requires guidance in order to grow... also the influence of psychotherapy in modern spirituality has helped understand some of this process... so a guide can 'measure' health/quality of recovery too!
