I have to agree with anvilhead, at least he is willing to attend some type of meeting, and at least he is willing to acknowledge that alcohol has affected his life.
More than likely he will hear people share their experiences about how alcoholics have affeced their lives in a way that he will identify with the alcoholic.
I have found that repeated exposure to stories about alcohol related problems causes a person to question the role that alcohol plays in their lives.
This is by no means a guarantee that this person will want to go to any length to succeed in the path of recovery, but it is a beginning.
If this person truly gets honest with themselves, they may see past their denial, and may be literally ready to take the first step (We admitted we were powerless over alcohol – that our lives had become unmanageable)
