"I don't drink or do drugs anymore," he told THR. "Being sober helps a great deal ... I remember looking at my life, my apartment, my dogs [when I was still using], and I thought, 'What's happening?' "

"I was at a party and deliberately bashed my head on the concrete floor -- like, 'Hey, look how tough I am!' And I came up, and blood dripped down. And then I did it again. I spent the night at St. Vincent's Hospital with a sock of ice, waiting for them to stitch me up," he said.
His struggle to stay clean was related to his public image and living in the Hollywood spotlight.
"I was so concerned what you thought of me, how I was coming across, how I would survive the day. I always felt like an outsider," he told THR. "I just lived in my head. I realized I wasn't going to live up to my potential, and that scared the hell out of me. I thought, 'Wow, I'm actually gonna ruin my life; I'm really gonna ruin it.'"
