Measuring time seems to be an aspect of the perpetual state of "recovering." It keeps me in that "never safe" area that I think rehabs promote.
AA does not promote that. It says, clearly and emphatically, that we can be recovered.
I think there's drama inherent in the "One Day At A Time" idea-- living on the edge, struggling, etc.-- that can be a hindrance to true recovery. It limits me from being free of the obsession, and keeps me in a place where I can justify any behavior by saying, "well, at least I didn't drink today."
