The AA "Big Book" contains the original 12 Step instructions for recovery.
These have been proven to have the highest success rates among chronic addicts like myself, since their publication in 1939. More info about why we use them in SAA is here.

While there is no substitute for reading from the book and marking it up with notes directly, some may have health challenges or want to enhance their recovery while doing tasks or sleeping.
These audio recoridings can help with that :)

I found these readings to be superior to the official recordings on the AA website.
Read by someone with feeling and emphasis, it just hits home for me, and hopefully for you too!

The Doctor's Opinion is a crucial text from the Big Book. In the original 1st publication, page 1 actually started here.
