Can't get enough sleep? Your problems probably pale compared to someone with Kleine-Levin syndrome - a rare disorder that can force someone to sleep up to 20 hours a day for weeks on end. Seventy percent of those afflicted are adolescent males. The episodes can come on quickly and are often associated with excessive eating, wild sexual urges, hallucinations, disorientation and even flu-like symptoms.
The disorder may be related to a malfunction of parts of the brain that govern appetite and sleep.
Once you have the disorder, you could be in for a long ride. The symptoms can take a decade or more to fully recede.
That's no fairy tale.
