Mathew Perry On Drug Use: 'I Was A Sick Guy' [VIDEO]

Matthew Perry recently opened up about the addictions that consumed his life during the most successful part of his career. The actor who achieved stardom with the hit comedy “Friends” -- which also starred Jennifer Aniston, Courteney Cox, Lisa Kudrow, Matt LeBlanc and David Schwimmer -- told ABC News how he became an expert at hiding his illness from his co-stars.

Perry, 43, said: “Mostly it was drinking, you know, and opiates. I think I was pretty good at hiding it, you know, but, you know, eventually people were aware.” He went through several stints in rehab, including a 28-day program in 1997 for a Vicodin addiction. On his road to recovery, Perry’s weight fluctuated, even falling to 145 pounds at one point, according to the Daily Mail.

Now he cringes looking at photos taken during some of his roughest days. Perry told ABC News: “I honestly recoil. It’s scary to look at that. I was a sick guy.”

The star, who is best known for his “Friends” character Chandler Bing, admitted that his fame is one of the things that helped him get on the right track. He said: “I couldn’t just walk into a bar. Everybody in the bar would go, ‘You, you can’t do that. I just read that you can’t do that. You can’t. You can’t.’”

Now that Perry is clean, he is helping other struggling addicts. The actor turned his old beachfront mansion in Malibu, Calif., into a sober-living home for men. “If you're thrown from treatment to the outside world, sometimes it’s too bumpy,” he said.

Perry is working with Earl Hightower, an addiction specialist, on the Perry House project. The duo even recently accepted the Champion of Recovery award at the White House. He joked in the ABC News interview: “Champions of Recovery, which is a very surreal thing, we’re award-winning alcoholics.”

Even though fans of “Friends” would love to see a reunion movie, Perry doesn’t think his old co-stars will be joining together on the silver screen: “[The TV show] was so terrific. If we did a movie and it sucked, then it would, you know, blemish it.”
