I plan to tell my friends I've quit drinking next time I happen to be around them and I'm offered a drink. When they ask I'll just say, "I quit a while ago, you didn't know?"
Luckily I managed my drinking around most of my friends (I was mostly a closet drinker). So my quitting won't be that big of deal. Around the other friends who are perfectly aware of my bad habit - they won't need to ask why! lol They'll already know why! But even more, I probably won't be hanging much around them anymore anyways.
