The chapter, "How Do You Know if You Need Help?" is worth the price of the book. It offers a checklist to help identify addictive patterns and warns that a thing or activity becomes addictive "when it alters your mood, if it provides a distraction from emotional pain, if you cannot stop it when you try, and if it takes up increasing amounts of your physical and mental energy."
You develop an addiction when something provides temporary relief from pain and you indulge yourself repeatedly to experience that relief. This results in an inability to control or stop what you are doing to gain relief, which in turn produces despair, guilt, and shame. You seek relief from the pain by repeating the addictive behavior or activity. The cycle is set.
How do you know if you have an addiction? And if you have, how do you overcome? In clear, brief, well written chapters the authors lead you through the process of discovery and recovery. You find answers to such questions as "What is your addiction?" "What set the addiction up?" "Where did your problem come from?" "Are your friends contributing to your problem?"
The only thing I can think of that would keep one from getting help from this book is denying that one needs help.
