NEW YORK CITY, New York –

Matthew Perry admits he does not remember much of the years he spent on Friends, and says he would never have been an alcoholic and drug addict if he had made different career choices.

“I didn’t remember the years I filmed Friends, and I can say I don’t want to. At the time I think I was trying to block it all out. When I look back now, and I watch the re-runs, I think ‘what a horrible show!’ Even the royalty checks can’t block out that garbage. If you were me trying to get through that shit, you’d have been messed up, too.”

Perry says that although there were copious amounts of drugs on the set, he did not partake until after hours. “Coke service was right next to food service, but I always stayed straight while we were filming. I’m a professional. Even though I was disturbed by what I was doing, the character I was playing, I stuffed all that down until later. I always started the night with booze. By morning I was crawling out of a k-hole and someone was splashing water on my face.”

In addition to Ketamine, the actor admits to using alcohol, Xanax, and cheap heroin. Perry says over time the drug use ate at his memory, and now the memories of being on the set of Friends are completely blocked out. “Part of it is post-traumatic stress. Most of it was the drugs. Almost all of it can be blamed on David Schwimmer.”
