Apart from becoming addicted to hard drugs at the height of her fame, Fisher also suffered from extreme mood swings. As has learned, she called her manic phase “Roy” and her depressive one “Pam.”

“Perfect example of a ‘Roy’ moment is when Moulin Rouge opened, she ended up staying and watching it twice straight through and then going to get a tattoo,” recalls Abe Gurko, Fisher’s former personal assistant, in the show teaser.

“’Roy’ needed to get action and go and do and be, and ‘Pam’ needed to just kind of sit and feel sorry and sob and stay quiet,” he adds.

While she was openly using cocaine and hallucinogenics, Fisher was also prescribed a series of medications to prevent her mood swings.

“The drugs Carrie was taking would reduce these mood swings, but the full effectiveness would only become apparent when she stopped taking them,” says Dr. Michael Hunter.

“When she wasn’t on the proper medication, she would go absolutely wild and crazy because she was wacko if she wasn’t on her meds!” says longtime family friend, Ruta Lee.

Autopsy Carrie Fisher airs Sunday, August 16 at 9:00 ET/ PT on REELZ.
