But in the meantime, absent answers to these questions, I'll respond in ways that I can. The bottom line: yes, we do potentially have some good resources to help this man. Given what you describe, it's likely he'll need other kinds of treatment and support as well, but our tools can help, either by themselves or as part of a whole regimen.
We have my guided imagery for Recovery from Alcohol & Other Drugs that gets good feedback from the recovery community.
In addition, there's a wonderful 2-CD set of guided meditations to go with each of the 12 steps of recovery, designed by experts in the field, Charles & Patti Leviton, that I highly recommend. It's called Inward Peace, Outward Power.
Those are the two most targeted resources we have for this challenge. But another title that a lot of people struggling with addiction really seem to appreciate and respond well to is Nurturing Your Inner Child by William DeFoore, also an excellent piece of work.
But I wouldn't load him up with all three at first. Better to start with one and see if he likes guided imagery as an approach. If so, he can work with one for a while before adding something else.
But chances are, he's going to need more than just audio recordings for help with this, at least initially, so if he can get a good evaluation - from a therapist or counselor who is experienced with chemical dependency, please!! – as well as some good support from a program, that would be good.
And keep in mind, he may need to start out in residential treatment to get properly launched into abstinence - and sometimes it takes more than one stay!
