Those revelations and more came from Murray, 60, in his first interviews since being released from jail in October, two years after he was convicted of involuntary manslaughter in Jackson's death.
"I did not agree with Michael on using such a powerful sedative for sleep," Murray told Australia's "60 Minutes" in an interview that aired Sunday.
"So what I told Michael is that we have to get you off that substance," Murray said. "However, I mean, to call it ideal or non-ideal, Michael Jackson is not a guy you can just say, 'Stop it.'"
Channel 9 Australia confirmed that Murray was paid for his interview on "60 Minutes."
In 2011, Murray was sentenced to four years in imprisonment for involuntary manslaughter after he treated Jackson with propofol, a powerful surgical anesthetic drug.
Murray, whose lawyers have filed petitions in Texas to have his medical license reinstated while his licenses in California and Nevada are suspended pending appeals, told "60 Minutes" that Jackson was a drug addict and administered the drug deadly dose of propofol to himself.
The former doctor told the UK's The Mail on Sunday that he 'reluctantly' gave Jackson a "miniscule" 25mg propofol injection, which would wear off in ten minutes, and sat by Jackson's bedside for more than half an hour as the singer finally drifted off to sleep.
"I left the room because I didn't want to disturb him. I believe he woke up, got hold of his own stash of propofol and injected himself," Murray told The Mail. "He did it too quickly and went into cardiac arrest."
He also said the pop star, who died at the age of 50, spoke to him on the day in 2011 that Murray was found guilty by a Los Angeles jury.
"Michael touched me," Murray told the paper. "He put his hand on my shoulder and he touched me and he talked to me. Michael speaks to me. He does."
In describing how close he says he was to Jackson, Murray claims Jackson was $40 million in debt and had unusual habits.
"Michael slept with dolls, yes," Murray told The Mail. "Is that normal? No. It's not normal. But if you understood the history of Michael as a child, and the things that he has encountered in life and you're willing to listen, you probably wouldn't judge him."
Murray also told The Mail that Jackson had trust issues.
"Michael trusted no one," Murray told the paper. "The bed chamber smelled because he did not even let maids in there to clean. There were clothes strewn everywhere."
Jackson's mother, Katherine Jackson, and his three children -- Prince, Paris and Blanket -- filed a wrongful death suit against concert promoter AEG Live LLC in 2010, claiming that the company was negligent in hiring Murray to tend to the singer. Earlier this month, the jury in the case ruled in favor of AEG.
Lawyers for the Jackson family did not reply to ABC News' request for comment.
