Sleep Disorders Reference Site

I've just stumbled upon the best reference for sleep disorders that I've ever seen. The address is http://www.webmd.com/content/article/105/107658.htm. The site covers a wide array of conditions including

• Sleep Disorders
• Insomnia
• Sleep Apnea
• Snoring
• Narcolepsy
• Hypersomnia
• Restless Legs Syndrome
• Periodic Limb Movement Disorder
• Sleep-Related Eating Disorders
• Drug- or Alcohol-Related Sleep Disorders
• Circadian Rhythm DisruptionParasomnias
• Sleep and Psychiatric Disorders
  

And within these categories, they cover:

Causes and Prevention
Making the Diagnosis
Treatments
Special Populations
Living With a Sleep Disorder
Toolbox
Sleep Disorders Bookshelf
To the Sleep Disorder Center

I read a fair bit of it, and it was clear and informative. I highly suggest this resource to people who are struggling with sleep disorders.
