Celebs Who've Gone Through Rehab

Back in 1998, Hollywood bad boy Charlie Sheen found himself in trouble again. He reportedly tried injecting cocaine and overdosed -- a violation of his parole. The incident quickly became public when his father held a press conference the next day urging his son to "accept recovery and become free." He was sent to Promises Treatment Center, but his first night in rehab didn't go so well. Sheen called a limo and bailed in his pajamas, but to his credit he returned the next day.
