Alcoholism and not remembering conversations?

by Glenda

My son is an alcoholic, he drinks a lot every day. I'm trying to get him to stop but he stops for a little while and then starts drinking again.

My question is often after he has been drinking we have a discussion and then the next day he says he doesn't remember our conversation? Is this part of his drinking problem? What causes it? What stage of alcoholism is he in if he stops remembering things?

Thanks
