I don't know much on the subject, but Fr. Meletios Webber (author of Bread & Water, Wine & Oil, and speaker of the Jottings from a Holy Mountain Podcast) wrote a book called Steps of Transformation: An Orthodox Priest Explores the Twelve Steps (Conciliar Press).
He also has a doctorate in counseling. I've not thoroughly read the book though.
Fighting the passions (not specifically "addictions")? That's kind of Orthodoxy's bread & butter.
