Matthew Perry says in his upcoming memoir his ever-changing appearance during the ten seasons of hit show Friends was down to which drug he was on at the time.
Perry writes in his memoir Friends, Lovers and the Big Terrible Thing that when he was carrying weight his drug of choice was alcohol, and when he was thin is was pills.
"When I have a goatee, it’s lots of pills," he wrote.
Excerpts from the memoir, which is an honest look back at his years of drug and alcohol addiction, are published on Page Six.
Perry, who played Chandler Bing on the US sitcom, says by the end of season three he was taking around 55 Vicodin a day. He says the opioid suppressed his appetite and made him vomit.
Perry says in the book that after filming the iconic wedding scene to Monica Geller he was taken straight back to rehab, Page Six reports.
Perry shot to fame along with he rest of the cast of Friends after it hit the screen in 1994. He says he used Vicodin, among other drugs, after it was prescribed to him following a jet ski accident in 1997.
He recently told People magazine he used drugs to deal with the fame that came with being a star.
