Two of Michael Jackson's former confidantes, medium Uri Geller and ex-bodyguard Matt Fiddes, say they tried in vain to keep the pop superstar from abusing painkillers and other prescription drugs suspected of leading to his death - but others in the singer's circle kept the supplies flowing. Geller, who said he suffered a terrible falling-out with Jackson several years ago over the issue, said Thursday that he often had "to shout at Michael, to scream at Michael" as he sought to confiscate the singer's stocks of medication during his travels in England. "Most of the people around Michael could not say 'No!' to him. He desperately needed someone there all the time who could say 'No!' and mean it, who could warn him of the dangers... and tell him the truth," Geller said. "The big problem was that many people wanted to help Michael, to save his life, but we could not be there all the time." Fiddes, an English karate instructor who worked as a senior bodyguard during Jackson's travels in Britain for a decade, said the pop idol abused prescription medications, not recreational drugs, and took so much that it could be difficult to wake him for engagements. "I confiscated packages and Uri did, too. I mean, Uri confiscated injection equipment from his room," Fiddes said in an interview broadcast Thursday by Sky News.
