sorry for your loss Flying.
When I quit I told everyone - but I'm not sure it needs to be that way.
These days 'no thanks I don't drink (anymore)' is all anyone needs to know.
I lost a lot of drinking buddies for sure - but my real friends supported me
I also gained a lot of new friends, and re-connected with a lot of old ones who I'd driven away with my drinking.
I don't think I lost anything at all
