While we won't know Michael Jackson's official cause of death for several weeks, but the King of Pop's nutritionist, Cherilyn Lee, says she warned the pop icon about certain drugs just five days before he died from cardiac arrest.

In an interview with ABC News, Lee, who is also a registered nurse, said Jackson was suffering terribly from insomnia and practically begged her for Diprivan - the brand name for Propofol, an anesthetic normally administered in hospitals.

"He said, 'Find me an anesthesiologist - I don't care how much money they want - find me an anesthesiologist to be with me here overnight and give me this IV.'"

Cherilyn Lee said the 50-year-old singer complained his body felt cold on one side and hot on the other, and that she told him of the potentially lethal side effects, including cardiac arrest if combined with other prescription drugs.

"I said, 'This is not a safe medicine, please don't take this. I've been around you long enough now, Michael, I love you as family. I would not give this to anyone.'"
