Supporting an alcoholic

[Almostdaylight]

Name changed for this as I'm a regular poster and this is quite sensitive.

I'm looking for some advice from people who have family members or friends who are alcoholics on how best to support someone.

A close male friend of mine (platonic friend) is an alcoholic. I've known him for about 12 years. He's always been a heavy drinker, but it's got steadily worse. For the last few years he's been drinking minimum of 2 bottles of wine a night (this is what he tells me, I know that in reality it's probably more than this).

He's functioning ok at the moment, has a well paid job and no money issues. He lives alone and is a good Dad to his 2 teenage DC who start with him regularly.

He's finally admitted to me he realises he's got a problem and he's going to 'do something about it and get his drinking to a moderate level'. I don't think he's going to achieve this and have gently suggested he should seek help. He doesn't want to go to AA as that's for '

I care about him and want to help, as he my friend and has been there for me over the years. At the same time I don't want to get too heavily invested in this. Any advice on how I can support him?
