35 of 48: Robin Williams, 59, first battled alcohol and cocaine addiction in 1983 but quit cold turkey after his friend John Belushi died of a drug overdose a few hours after they had snorted cocaine together at a hotel. Williams was sober for 20 years but relapsed and sought treatment in 2006 after a 3-year drinking binge. He told People magazine in December 2009, "I found myself drinking to blackouts. It's like your brain going into witness protection." (Photo courtesy of Steve Rhodes)
