Regrets? Stevie Nicks has only one.

The 62-year-old singer tells FOX411's Pop Tarts that after seeking treatment for cocaine addiction in 1986, a doctor prescribed her Klonopin, which is typically used to treat seizures and panic disorders.

"The only thing I would change is walking into that psychiatrists office who prescribed me Klonopin," Nicks now says. "That ruined my life for eight years."

The prescription drug only made matters worse for the Fleetwood Mac frontwoman, who says it prevented her from being truly sober.

"That was just a stupid doctor making a groupie mistake and just wanting me to come in there, tell him about all my music friends and young Hollywood and that nearly ruined my life and nearly killed me," Nicks recalls.

"That's eight years that I could have. God knows, maybe I would have met someone, maybe I would have had a baby," she wonders. "That was my prime eight years. That was a big mistake. Everything else was exactly how it should have been."
