NEW YORK -- The actress who played Marcia Brady on the classic television sitcom "The Brady Bunch" is revealing some serious issues from her past.

Maureen McCormick told People magazine that she used to snort cocaine and suffer from bulimia.

McCormick, 50, said that the eating disorder came first, when she went back to public school when she was 17.

Then a boyfriend introduced her to cocaine.

McCormick said it became clear she has an "addictive personality."

After several relapses, McCormick said she cleaned up through therapy and faith.

The actress played Marcia on "The Brady Bunch" from 1969 to 1974, and appeared in variety shows and television movies based on the series.

She has also guest-starred on several television series including "Fantasy Island," "The Love Boat," "Touched by an Angel" and "Moesha," and had a recurring role on the daytime drama "Passions."
