Can you tell me how to help my alcoholic mom, who denies having a problem?

By helping yourself. Ultimately, only the individual can decide if they have a problem and want to change. Their loved ones usually have a very hard time accepting this, and many never accept it. Alanon, a family program separate from aa, has meetings that can help -you can find it in the white pages under hotlines and helping lines. Being loving and supportive, staying away from blame and guilt, are your best tools.
