I agree with Anvil that you should just acknowledge his feelings & let him know that you are there IF he wants to talk about it. Have you mentioned this website to him? Is he going to AA at all? The most comfort I've found is talking with other addicts working towards the same goal. Someone who understands just how much of an accomplishment it is to drive past a liquor store without stopping or to come out of a grocery store without wine. Something that non-addicts wouldn't think twice about.
