There are/were alcoholics in my family. My advice? Do nothing other than telling the person you think they have a problem and are willing to help them ONLY with solving their problem. Do not offer any other help at all because it will only enable them to continue. Sounds harsh but talk to any addict who has successfully made it to the other side and they’ll readily admit that they would do anything to continue their habit. Until they admit they have a problem and want to change, there is nothing you can do. That would be my advice if the person didn’t have minor children. They are only hurting themselves. If the person had minor children, it would depend on the situation. It gets even stickier if it’s a family member with children. Unfortunately I have experience with that.
