(CNN)Jamie Lee Curtis is proud to be nearly 20 years sober but says it hasn't been easy.
The actress, who currently stars in "Halloween," told People she first became addicted to pain killers in 1989 and hid it for ten years.
"I was ahead of the curve of the opiate epidemic," Curtis said. "I had a 10-year run, stealing, conniving. No one knew. No one."
This is not the first time that Curtis has opened up about her addiction. In 2001, Curtis told CNN, "I don't know if any of us can really explain what addiction is exactly, because I think it changes with each individual. I think what we can talk about, is really that there's hope to recover from it."
