"I remember ... using my fingers, the small fingers of a child, to dig the pills my mother had tried to swallow out of her mouth while my father held it open and told me what to do," Moore, 56, said in the magazine's October issue, where she spoke with fellow actress Lena Dunham. "Something very deep inside me shifted then, and it never shifted back. My childhood was over."
Moore also reflected on her own battles with addiction and her-off-and-on relationship with sobriety. Throughout her fluctuating career, the former Mrs. Ashton Kutcher has found herself making headlines for substance abuse, but said she now finds solace in staying clean.
"In retrospect, what I realized is that when I opened the door (again), it was just giving my power away," she said.
"I guess I would think of it like this: It was really important to me to have natural childbirth because I didn't want to miss a moment. And with that I experienced pain. So part of being sober is, I don't want to miss a moment of life, of that texture, even if that means being in ... some pain."
Moore's book, "Inside Out," hits shelves on September 24.
