Interesting topic.
What about those who say, just for today? Is that not leaving the door somehow open? I think whatever keeps us sober is good, maybe my door wasn't closed when I thought it was.
At first, all I knew was for some reason, I never wanted to drink again. I woke up one day and thought enough is enough. But for me (and it's just me), I had to move past saying just for today after I had a.slip a month ago.
To use your analogy Mecanix, the door feels closed now, but I don't feel it as a sense of finality, like a loss. It's just a fact...My body chemistry has passed the point of no return...my system is so screwed now that the messages alcohol send in my biochemistry are just all wrong.
I guess it's acceptance. Feeling comfortable with the facts. Not sure.
