There's a Kundalini Yoga book that maybe can help you. There are lot's of protocols for different phsychiatric disorders, one of them addictive and impulsive personality dissorder. I have not tried the protocol for addictions, but have been having success for treating phobias and neuroses.
It is called Sacred Therapies: The Kundalini Yoga Meditation Handbook for Mental Health.
If you're sceptic, maybe check Leo's video on Yoga. Hope it helps.
