Nurse nutritionist Cherilyn Lee testified for the defense - Day 16 -

Cherilyn Lee, a nurse who practices nutrition and natural remedies, said that she worked with Michael Jackson to help his fatigue and insomnia from February through April of 2009.

Lee also testified during the preliminary hearing that Jackson asked her for propofol as well while she treated him in 2009.

During her testimony today, she said that after two months of using IV infusions of vitamins, sophisticated vitamin smoothies and bedtime teas, Jackson began asking for more help, Lee testified.

"His complaint was 'I have a problem sleeping and all the natural remedies and everything you're doing is not working,'" she said. "When I need sleep, I need to go to sleep right away."
