Query: HIGHLY DISAPPOINTED!!!

What's cooking!? As you may have surmised from the above title, I was disappointed in having just purchased this book. Firstly, I was unable to find a listing for NARDIL (Phenelzine). That was my primary reason for purchasing this book. While MAO INHIBITORS were vaguely mentioned throughout the book, it was not given its own entry. Secondly, the title of the book is a little misleading. One is led to believe that the entire scope of the book would deal with ADVERSE REACTIONS, INCIDENCE REPORTING, easily categorized REFERENCE CHARTS which lists all the WORST & BEST PILLS, etc. None of this was to be found. Instead, this was nothing more than a regular drug reference book with a few pages dedicated to generalized discussions on adverse reactions and preventions. I find it highly ironic that a book which is titled "WORST PILLS, BEST PILLS" would choose to omit NARDIL of all pills. The same NARDIL that is infamous for its life-threatening adverse reactions.
