Him saying "AA just made him want to drink more" is a cop out. This is a program that has worked for 85 years and the 12 steps are the best way to live. I myself have 32 yrs sober and a member in the fellowship in good standing. He needs to want to try anything to stop, Its either life or death. I found that a life of drinking just made me numb and dumb. Its gives you tunnel vision and Is an immature way of coping with life's problems. It creates a mental obsession and tells you that you can keep drinking. He needs to try AA for a Good 6 weeks.
Best of luck.
