The 8 Mile actor nearly died from an accidental overdose.

'In 2007, I overdosed on pills, and I went into the hospital,' he told Men's Journal in 2015.

'I was close to 230 pounds. I'm not sure how I got so big, but I have ideas.

'The coating on the Vicodin and the Valium I'd been taking for years leaves a hole in your stomach, so to avoid a stomachache, I was constantly eating — and eating badly.'

Exercising ultimately turned his life around.

'When I got out of rehab, I needed to lose weight, but I also needed to figure out a way to function sober,' he added.

'Unless I was blitzed out of my mind, I had trouble sleeping. So I started running. It gave me a natural endorphin high, but it also helped me sleep, so it was perfect.

'It's easy to understand how people replace addiction with exercise. One addiction for another but one that's good for them.'
