I got the same thing from a friend of mine. I was having lunch with her and told her that I have quit drinking for good. She said what many say "Just have one or two". I didn't argue with her, I just let her say what she said, and will do my own thing.
A couple of days later it was her birthday and a few of us got together at a Martini bar after work. I ordered tonic water, and she never questioned it, nor did anyone else at the table. I had a great time because the conversation was a lot of fun. I was also happy because at no time in the evening did I actually crave any of the drinks, even though I was surrounded by them.
