Sanctification Question

Here's the scenario.

A young man comes to you and confesses that he is in bondage to something addictive (whether drugs, alcohol, sex, pornography...whatever.)

He is in distress and near despair because of his lack of victory in this area.

He is a confessing Christian, and aside from this confession, has never seemed to bear the fruit of a false convert. There's nothing you've observed in his life that would've led you to suspect that he's anything other than a growing, though imperfect, sincere believer in Christ.

Now that he's laid bare his soul to you, his desire is freedom from this sin.

What is your counsel?

(The reason I ask is because I was "raised" as a baby Christian with a Pentecostal view of sanctification, and am interested in other ideas. I'm not so much interested in your theology of personal holiness as I am what your specific counsel to a man like this guy above would be. I'm interested in how the rubber meets the road in your theory of sanctification.)

So...play nice and try to keep responses to something less than thesis-length.
