If you’ve ever stared at the ceiling wondering why sleep won’t come, you’re not alone. In fact, six out of 10 adults in the United States don’t get enough sleep. That’s according to the National Sleep Foundation. This hour, we hear from someone diagnosed with insomnia and a sleep expert. They'll help us understand why rest feels so out of reach, and what might help us drift off. GUESTS: Jennifer Senior: Staff writer at The Atlantic, author of: "Why Can't Americans Sleep?"
