Eminem has regularly alluded to his previous addiction to prescription medicine, which began during his 8 Mile filming in 2002.
"It's very similar to what I've read about Michael," he said. "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 (drugs). That's what I was doing."
Eminem added that he wasn't taking prescription drugs to get high, but was "taking them to get normal."
