Melody Beattie also wrote Codependents Guide to the 12 Steps and that book has always helped me re-work my steps. My first time through was with my sponsor, and I highly recommend that, but for those who cannot get to meetings I think this would be very helpful.
This link is new to the sticky threads at the top of this forum. It used to be there and I could not find it this morning, so I am glad you asked because now it is up there again.
Good luck.
