If you've seen the Elton John biopic "Rocketman," you know that he struggled with alcohol and substance abuse but finally decided to kick the habit in 1990.
On Monday, he marked 29 years since he got sober.
John posted a photo of his AA sobriety medallion, which has the words "To thine own self be true" and "unity, service and recovery" engraved around the roman numeral for 29.
"29 years ago today, I was a broken man," he captioned the photo. "I finally summoned up the courage to say three words that would change my life: 'I need help.'"

John recently told the Times of London that the new song he and Tim Rice wrote for the new "Lion King" movie, "It's Never Too Late," accurately describes his own journey to sobriety.
"It's never too late to change, and that's what Simba goes through in this whole journey," the singer told the outlet.

I had an epiphany in 1990," he continued. "This is about having an epiphany in your life and saying, 'I need to take a fresh look at what I'm doing.'"
John previously said that the epiphany came following the death of teenage AIDS victim Ryan White, who'd contracted the HIV virus through a blood transfusion. White died in April of 1990, and John said, "Six months later, I was in rehab."
