Almost have 13 months and my wife is the only one that knows that I quit and why. Even she and I really haven't talked about it much since the decision was made. I am sure plenty of others have noticed that I am not drinking anymore. Most never asked about it. The ones that did seemed satisfied when i simply told them that I was fine with diet coke
Don't make it a bigger deal than it is. Just be happy and keep the stress level on minimum. You'll know what to do if/when the time is right.
