Welcome to SR! Now that you are retired you have more time on your hands and probably a few bucks in your wallet, a dangerous combination for an alcoholic. Have you thought about AA? There are meetings everyday and you will meet a bunch of people working to stay sober. I know several guys in AA that have learned it's possible to fish and play golf with other guys without a beer in their hand.
There is also a story in the Big Book about a guy who didn't start drinking until he retired, then it was full speed ahead to alcoholism. Interesting read.
