Welcome upontheroof, my drinking patterns share some similarities to yours and I'm only a few years younger than you.
I know what you mean about the embarrassment and injuries, it really is the worst thing and totally not worth it. I've now gotten 20 sober weekends under my belt and I'm so happy to be off that hamster wheel and truly living and enjoying my weekends.
You'll find lots of support here. Glad to have you!
