"I don't drink or do drugs at all anymore," he says, saying he hasn't used them since being 29. "Being sober helps a great deal."
So what kind of silly things did drunk Bradley used to get up to?
"I was at a party once, and deliberately bashed my head on the concrete floor, like, 'Hey, look how tough I am!'" he says.

"And then I did it again," he explains. "I spent the night at St. Vincent's Hospital with a sock of ice, waiting for them to stitch me up."
The actor confessed that the catalyst came when he realized that the drink and drugs could compromise his career and at that point he just stopped everything.
"I always felt like an outsider. 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 going ruin my life; I'm really going ruin it.' "
Good thing it all worked out, Hollywood is a much fitter place with Bradley Cooper in it!
