If you have trouble sleeping, you're definitely not alone. More than half of US adults experience some symptom of insomnia at least a few nights a week. To help us get more of that elusive thing called sleep-and address issues beyond insomnia, like snoring, "monkey brain", and difficulty waking-we enlisted the help of a sleep specialist. Here's what we learned. [Lifehacker]
Not to scare the living crap out of people, but extended periods of little rest (3-4 hours a night) can trigger a hypo/manic episode, not to mention slower reaction times, worse driving, and damaging your immune system.

(I had a no sleep induced hypomanic episode many years ago that culminated in a half assed suicide attempt, two weeks in a locked psych ward, and untold thousands of dollars in medical bills. At the time, I was seeing a doctor who didn't take the insomnia seriously, and I really think some judiciously, carefully prescribed sleeping pills could've stopped the whole thing.)
