Summarize the following:
Be available to listen when this person needs a friend. Even if the person does not want help now, they may want some support in the future. Let them know that while you don't approve of their alcoholism that you are available to talk and listen if they need it. Communicate that you are willing to be a friend when they need friendship. Share your thoughts and feelings honestly with the addicted person, letting them know how you feel. Put the focus on you and not on them, as this can cause guilt or shame. For example, instead of saying, “You're destroying yourself and making bad decisions” say, “I don't get to see you anymore, which makes me sad. I miss having you as a part of my life.” Let the person know you are worried and are impacted by their drinking. Express your willingness to be supportive as well. Say, “I really don't like how alcohol has impacted our relationship. While this is painful for me, I want to support you because I care about you.” If the person expresses interest in seeking treatment, offer to help them however you can. Help them look up treatment facilities, detoxification programs, support groups, or whatever else they are interested in exploring. Offer to drive them to appointments or support them in certain life changes.  If the person isn't quite ready for help, make one offer, then wait for them to ask you. If you constantly offer help, the person may become off-put by you and your good intentions. Get informed on local resources for alcohol addiction. For example, look up community groups for alcoholism, treatment specialists, and treatment programs. That way, you can be ready to share information with the person.
Be available to listen. Express honesty. Offer to help.
