I am glad you decided to give AA another try.
I too read the BB before and I swear it is not the same book. It is so much clearer then last time. It makes sense this time. I go to a BB meeting and I love it. I really get a lot out of it.
I have heard people with over 20 years sobriety make comments that they too feel the book changes as more time goes on. I think it comes down to were are in our journey.
One day at a time and keep us updated.
