Sleepy, grumpy... doc? (L.A. Stories).

Stephanie Luciano stays up until 2 am. on most nights, club-hopping.

"I rely on Red Bull and coffee because I work all the time," says the 28-year-old talent rep for The Agency Group. "I work at home. I work when I go out. So it's not a job, it's a lifestyle," she said.

Luciano has become the L.A. poster child for the National Sleep Foundation, a Washington-based non-profit that studies the effect of sleep -- or lack of it -- on modern society.

"There's a lot of emerging science on the relationship between sleep, health and disease," said Richard Gelula, the foundation's executive director, who admitted to not getting enough sleep himself. "People basically dismiss the importance of sleep and think they can squeeze an extra hour out of their day?."

Luciano admits she's never been diagnosed with a sleep disorder, eats healthy and works out. In fact, it is her job representing DJs that keeps her up late.

Asked about the newest poll from the National Sleep Foundation that attributes anger, stress and obesity, in part' to inadequate sleep, Luciano replied: "I guess that's true. But the fact is being in any metropolitan city in the entertainment industry means you don't get sleep."
