Early in my sobriety, probably after 10 or so days sober I drank again over a weekend when my Missis was away.
I didn't exactly lie about it, but I never told anyone either; so I'm not sure if that counts. I'm not happy that I did it, but I've put the knowledge of it into a 'box' in my head and it's staying there since I don't think it really matters.
I've adjusted my AA birthday to suit when I had my last drink, but even by typing and justifying my actions I guess the box is opening.
However, my Missis is away this weekend and I've not had the obsession to drink; nor have I drank; so I'm doing something right.
Personally, I don't think it's time away from your last drink that makes you; it's how you feel about your sobriety; and I feel good about mine. It's been over five months now.
