I have the original book, should I still buy the updated version?

Yes.  The second book is a more detailed and comprehensive view of the protocol and includes all the new information I have learned since I wrote the original book.  The second edition is double in size and covers anxiety, hyperactivity, and aggression in much greater detail.
