I've been coming to this way of thinking, too. While also noticing how amazingly life can flow when it's flowing--in any direction--good stuff, painful stuff, challenging stuff, grief stuff, miraculous stuff, sometimes all together.
I don't really count days either. For one reason I'm on suboxone so I think of it a little differently--definitely as recovery just not day counting. I also know my own perfectionistic/fanatic tendencies and know I would get too caught up in the "perfection" of days and that would make me hate myself and fail.
Finally, I have slipped while on suboxone so I don't have a "perfect" clean time. But I finally realized that I too really needed to celebrate the stuff that counts, the milestones that really have meaning for me. And so I am celebrating almost six months off oxy and five and a half off dilaudid. As these were my primary, absolute drugs of choice, it really is a BIG DEAL and something to celebrate!
So, hooray for me! And all of us!
