I have done the "girls night out" stone cold sober. I don't feel like I can or should give advice - as I am coming out of relapse of sorts, but the "girls" were slobbering and loud and so obnoxious that I felt uncomfortable not because I wasn't drinking, but because I was kinda embarrassed for them. Go figure. So, I drove some people home and I felt like a million bucks the next am and went for a long run. Best of luck to you.
