Robert Downey Jr's Burger rehab

Robert Downey Jr. says fast food chain Burger King helped him beat drugs.The 'Iron Man' actor - who was arrested in 1996 on drug and weapons charges, spent nearly a year in prison in 1999 and was arrested again in 2000 for a hotel drug sting operation - has publicly thanked the eatery for making him realise he needed to kick his habit.Recalling an incident in 2003 when he was driving with "tons of f***ing dope" in his car, Robert says he stopped at a Burger King to get a burger, but the food had such a bad effect on him he thought he had overdosed.He told Empire magazine: "I have to thank Burger King. It was such a disgusting burger I ordered. I had that, and this big soda, and I thought something really bad was going to happen."Robert revealed he then threw all his drugs into the sea and immediately decided to turn his life around.The 43-year-old actor also admits his 'Iron Man' character Tony Stark's request for a cheeseburger after being released from his terrorist captors is a reference to his own experience.Robert can next be seen starring alongside Ben Stiller in controversial comedy 'Tropic Thunder'.
