Matthew Perry
Perry enjoyed a dramatic rise to fame in the ’90s as he starred as Chandler in Friends. Everything seemed perfect in his life but the reality was very different. In his memoir, he revealed that he went to rehab 15 times and attended thousands of AA meetings. Oxycodin almost killed him when his colon burst.

He also admitted that he faked pain at one rehab in Switzerland to receive ketamine and morphine shots. Furthermore, Perry explained that he had noticeable weight fluctuations during Friends because of his drug use. It seems like an endless battle for the star (via Variety).
