Didn't tell my wife until the 7th day. But I hid my drinking so, even tho she knew, it was like I had to confess first. I try hard not to think too much into the future, I had to accept that I'll never drink again and that's easier if you keep it in the now. Of course there are always those events you can't avoid and will have to have a plan for. But there's nothing to gain from worrying about something happening months or even weeks from now.
It a great decision you've made. I wish I had the same sensibility at your age.
