Mötley Crüe bassist Nikki Sixx marked his 25th sobriety anniversary on Thursday.

"It's hard to wrap a lifetime of lessons into a few paragraphs, but one thing has never changed: sobriety gave me a life I never imagined was possible," Sixx wrote in an Instagram post. "It gave me my family. It taught me how to be present instead of just existing. It showed me what it means to be a husband, a father, a friend, and a bandmate—not perfectly, but honestly."

Sixx documented his struggles with drug addiction in his 2007 book, The Heroin Diaries, which was released alongside the debut Sixx.M. album, The Heroin Diaries Soundtrack.

Reflecting on the milestone, Sixx added, "If my story helps even one person believe there's another way, then every scar has found a purpose. Twenty-five years later, I don't celebrate perfection. I celebrate progress. I celebrate love. I celebrate the people who walked beside me when I couldn't walk alone."
