The rapper, who overcame his addiction to prescription drugs, said that during his Anger Management tour that he was 'f**ked up every day'.
He told Rolling Stone: 'I was taking so many pills that I wasn't even taking them to get high anymore. I was taking them to get normal... I want to say in a day I could consume anywhere from 40 to 60 Valium. And Vicodin? Maybe 20, 30.
'My everyday regimen would be, wake up in the morning and take an extra strength Vicodin... and it'd be Vicodin throughout the day.
'Then, as the evening crept up... I'd start with a Valium or two, or three, or four. And every hour on the hour, I'd pop four or five more. The Ambien would put me over the top to go to sleep.'
He added: 'Toward the end, I don't think the s**t would put me to sleep for more than two hours.
'It's very similar to what I've read about Michael [Jackson]. I don't know exactly what he was doing, but I read that he kept getting up in the middle of the night, asking for more. That's what I was doing.'
