So, you have sleep problems. You’re not alone. About 70 million Americans suffer from sleep problems. Even many celebrities have had to face the reality of dealing with a sleep disorder.

When Rosie O’Donnell was on The View, she talked about her diagnosis of sleep apneaO’Donnell said that she had been turning and snoring like a buzz saw in bed, so she felt it was time she figured out the cause. O’Donnell said that she didn’t know that she had sleep apnea, but she had suspicions and a home sleep apnea test confirmed her suspicions.

Some other celebrities that have admitted to battling sleep apnea include Shaquille O’Neal, Regis Philbin, Roseanne Barr and Daniel Lawrence Whitney, better known as comedian Larry The Cable Guy.

Lady Gaga and Madonna are often compared to one another and both have admitted battling insomnia.

George Clooney has also freely admitted to dealing with insomnia. During an interview with the Hollywood Reporter the actor admitted that he wakes multiple times a night and loathes going to bed without the TV on. “Turning off the television causes me to think, and once I start that vision roaring, I have a very tough time getting to sleep. With the flickering screen, I’m able to numb out. Even then, without question, I wake every night five times.”

Jimmy Kimmel has been very open about his struggles with narcolepsy. He told Esquire magazine that he had no idea he had the sleep illness, but “I did know that every afternoon between about three and six, I would get very tired for no reason. I would doze off in meetings, watching TV, even driving. You know how when you’re regular tired, your whole body is tired? With narcolepsy, just the inside of your head is tired. It’s like somebody’s gently sitting on your brain. You have almost no focus. All you’re thinking about is not falling asleep.
