I am eagerly waiting audiobooks for Steve O's The Great Pain Deception and Dr Schubiners book. While looking on Audible, I saw Steve had a book labeled "Back Pain Permanent Healing" Has anyone listened to this one? If I already have GPD is this worth it? I really like audiobooks because I can listen while driving,etc ... it saves a LOT of time. I've listened to Dr Sarnos Healing Back Pain book tons of times now.
