Desperate for sleep, Michael Jackson reportedly turned to Sherilyn Lee to help him find Diprivan, a potent sedative that's used mainly in hospitals Lee, who claims to be Jackson's former nurse, says Jackson was familiar with the drug.

"When it drips in my body, the first drip, I am asleep, and all I want to do is sleep."

Texas Health Dallas sleep expert Dr. Nabeel Farah says insomnia is a huge problem by the time patients get to him, they've tried everything.

"They've tried over the counter sleep aids, they've tried borrowing their aunts Ambien, they'll take two of the sleep aids their doctors have prescribed previously."

Dr. Farah says some patients self medicate before they arrive for an appointment. Lee says Jackson told her that normally prescribed sleep medications didn't work. Dr. Farah says the drug Jackson allegedly wanted, knocks you out, reduces blood pressure and can make you stop breathing.

"I can't think of any circumstance that you would use that medicine outside of an ICU or a surgery setting."

Jackson was about to start a fifty date concert tour, this after financial debts and courtroom battles. Dr. Farah says stress and exhaustion can exasperate insomnia. Sometimes desperate people do desperate things.

"Sometimes people over medicate and they know it's dangerous, they feel so desperate that that is what they do."

Lee says sleep was Michael Jackson's dream.

"You know, I just want to go to sleep. I want to sleep eight hours so I can be refreshed the next day."

Experts say if Jackson did use the drug Diprivan, it will show up in the toxicology report.
