Eminem suffered massive memory loss because of his five-year battle with prescription drugs and still can't recall many key events from his career.
The Stan rapper struggled with a raging addiction to pills including sedative Ambien, and the hip-hop star blames the drug for erasing years of his life.
He tells Rolling Stone magazine, "A lot of my memory is gone. I don't know if you've ever taken Ambien, but it's kind of a memory-eraser. That s**t wiped out five years of my life. People will tell me stories, and it's like, 'I did that?' I saw myself doing this thing on Bet (TV network) recently, and I was like, 'When was that?'"
