Michael Jackson pleaded for a powerful sedative to cure his insomnia ahead of his comeback tour, a nutritionist has said.
Cherilyn Lee, 56, a nurse and nutrition specialist in California, said the tragic singer had asked to be prescribed the drug Diprivan - despite warnings it could have harmful side-effects.
Ms Lee said she received a call from a member of Jackson's staff four days before the star's death on June 25 and told them the star required immediate hospital treatment.
She said the conversation made her fear that "somebody had given him something".
"He called and was very frantic and said: 'Michael needs to see you right away'.
"I said: 'What's wrong?' And I could hear Michael in the background - 'One side of my body is hot, it's hot, and one side of my body is cold. It's very cold'."
She told the staff member that Jackson needed hospital treatment "right away".
She added: "At that point, I knew somebody had given him something that hit the central nervous system."
