Stahl's Illustrated Sleep and Wake Disorders

The 2 star rating is for the price! This book has 123 pages, 23 of which are references. This book is worth about $10, in my opinion. But $40?! No! I should have read the description a bit closer.I haven’t started reading the book yet, but am sure it’ll be helpful, as are all of Stephen Stahl’s books. It shouldn’t cost an arm and a leg though.
