"She said, ," Lloyd wrote. "It stunned me, because I didnt think what I was doing was a problem."

But he quickly noticed that his substance abuse eventually began affecting his life on screen and off.

"At some point, it became clear that I ," Lloyd continued.

In 1993, Lloyds psychologist arranged for him to enter treatment in Arizona. He recalled being "completely wasted" when he boarded a plane to a treatment facility, where he refused to stay and ran into a barbed-wire fence after leaving.
