A nurse practitioner Cherilyn Lee, who took the witness stand on Monday, continued her testimony of the details of her treatment of Michael Jackson, on Tuesday, Oct. 25.

Lee said Jackson asked her for the powerful anesthetic propofol to help him to sleep because he was frustrated with Lee's natural remedies.

What I need is something that's going to help me fall asleep right away, (and) the only thing that will help me do that is Diprivan, Lee recounted Jackson's request in her last house call to Jackson's home in April 2009. Diprivan is a brand name for propofol.

Lee then learned that the drug was dangerous to use at home and so she refused to give it to Jackson.

However, Jackson insisted propofol was safe if only he had a doctor to monitor him with the equipment while he slept.

Ignoring Lee's warning and efforts to save him from the drug, Jackson fired the nurse eventually.

Lee's came into Jackson’s life at the beginning of 2009 and left just before Dr. Conrad Murray arrived.

Lee became tearful twice during her testimony as she recalled how she had warned Jackson not to take the drug.

Lee was called to the stand by Murray’s defense, but her testimony was often mixed and even worked against the defense.

Randy Phillips, the head of AEG Live unveiled the reason why the pop icon are so desperate for some drug to help him sleep.

Jackson feared he would miss more rehearsals for lacking enough sleep and it would get his This Is It tour canceled by promoters.

If the tour was canceled, the King of Pop would have to pay a large amount of money for all of the production and rehearsal costs, which would leave him a very, very poor man.

Phillips also mentioned Jackson's visits to another doctor - dermatologist Dr. Arnold Klein.

The defense hopes the testimonies of their witnesses will cast Jackson as a patient who was blind to the dangers of the strong anesthetic.
