Kelly Osbourne became addicted to Vicodin pills, taking up to 50 tablets a day, by the age of 17. She says her mother’s cancer diagnosis made the problem worse. After her fourth stint in rehab in 2009, the former Dancing with the Stars contestant and E!’s Fashion Police panelist said she finally felt optimistic about her chances at recovery. “After 30 days, I left rehab. For the first time, I felt hopeful. I knew I’d been given another chance at my life, at my career, at happiness. I wanted to grab it,” the 26-year-old wrote in her book, Fierce.
After struggling with alcoholism and cocaine abuse in the 1980s, Robin Williams says the overdose of fellow comedian John Belushi and becoming a father served as his wake-up call to get help. “It was great to have full sentences once I cleaned up. It was also great to be aware of the experience of a child and watching him grow, which is another amazing experience,” Williams said in 2001 on Inside the Actor’s Studio. However, in 2006, after more than 20 years of sobriety, Williams checked himself into rehab for alcohol abuse. "It's hard admitting it, then once you've done that, it's real easy," Williams told ABC’s Diane Sawyer that year. "You think people don't notice. Then you find out later, 'We knew. … You went outside naked.' No, I didn't. But even the dog was like, 'What's wrong, boy?' Humiliation gives you humility."
