That's great news, 439Trish! Congratulations on your achievement! Such a wonderful death defying act you have committed.
I don't think you are missing anything as counting days has its detractors and proponents, even among AVRT types. For me, I like to think of quitting drinking as being an event, a completed action in the past, that marks me as BADASS IN YOUR FACE I'M DOING THIS BECAUSE I DESERVE BETTER AND BECAUSE I SAID SO DAMMIT. BOOYAH. Another day doesn't make me any 'quittier' than I was yesterday. Even so, I mark my anniversaries with satisfaction and pride.
