I have only told my partner, my best friend and a coworker because he shared with me that he was in recovery a long time ago. I haven't told my sister and not sure I would... She had her own crap going on all the time.
People know I don't drink now.. Thought I would clarify. At work, I say that I'm off the sauce and then some pretend to faint... If asked, I say it is for my health which is 100% accurate.
