10. Robin Williams
The death of the late Robin Williams was devastating news to the world. He left us so many memories through his entertaining movies and TV shows.
The young Robin was already struggling with addiction problems. But he managed to stay sober for about twenty years since 1986.
He fell off the wagon in 2006. He went into rehab. He was reported to check himself at the Hazelden Addiction Treatment Center.
It was a huge wake-up call to him when his friend, John Belushi, died of a drug overdose. Since then, until the day he passed away, he stuck with his long-term sobriety.
