I think we're all in agreement actually. Why? Because we are describing our personal experiences. There is no wrong or right answer to this, especially if whatever "bottom" took place led us to seek help.
Even the Big Book states that one of the goals of the book itself was to "raise the bottom" so that some would not have to lose all.
When my last run ended I still had more "stuff" than I had ever had. Car, some money left, a business...but the shame, guilt and pain I was feeling was greater than any before. It was MY bottom.
But I also believe that had I just rested up for a few days and went right back at it, then it really wasn't a bottom after all. Just some more denial, rationalization and justification.
How does one "know" if they hit bottom? I firmly believe it's what we do the day after.
My actions will be so loud that you won't be able to hear whats coming from my mouth...
