Local Community Treatment Centers

What exactly is a man in his mid 70s who is drinking too much supposed to do. My uncle retired only a couple of years ago but since he did he’s come adrift and all he does every day now is sit in the local hole in the wall bar and drink quarts of beer from mid morning onward. I’ve talked to him about it and he says he knows he’s got a bit of a problem but he doesn’t know what to do about it. He’s a really good man but he’s a bit cranky and set in his ways he’s just not going to do well in any situation with younger people like AA. He’s not well off but he needs some help and I am not sure he should be living on his own really. What can a senior citizen on a pension do when he needs serious help with his drinking?
