The rapper, who overcame his addiction to prescription drugs, said that during his Anger Management tour he was 'f****d up every day'.
He says he was just two hours from dying when he overdosed on methadone, admitting: 'I'd done the equivalent of four bags of heroin.'
'I was taking so many pills that I wasn't even taking them to get high anymore,' the rap superstar told Rolling Stone magazine.
He said that drugs became a problem when he started taking Ambien to rest on the set of 8 Mile.
'I was taking them to get normal. I had to take ridiculous amounts. I want to say in a day I could consume anywhere from 40 to 60 Valium. And Vicodin - maybe 20, 30. I was taking a lot of s**t.'
