It's great to have you with us, MrPL. You are never alone - there's always someone here to listen & understand.
Be glad that you've come to this conclusion about drinking. Some never see what it's doing to their life. Or - like me - they keep on into middle age insisting they will one day magically manage it. I crossed the line from social to alcoholic drinking decades ago. I wish I'd done what you are - and acknowledged that I was in danger. You won't waste the years & opportunities that many of us did. You can do it.
