While the world of celebrities is filled with stories of those who lost their battles against addiction, not all celebrity addictions have an unhappy ending. Here's a look at some stars who have fought addictions and won.
As a rising comedic talent whose career was taking off thanks to his standup routine and "Mork & Mindy," Robin Williams developed an addiction to cocaine and alcohol in the 1970s and 1980s. He has said the death of his friend John Belushi helped convince him to stop using drugs. In 2006, he relapsed and checked into a treatment center for alcohol abuse and has said he's been sober since.
