Rob Lowe just reached a major milestone.
On May 10, the 57-year-old actor took to Instagram to celebrate 31 years of sobriety.
"Today I have 31 years drug and alcohol free," he wrote. "I want to give thanks to everyone walking this path with me, and welcome anyone thinking about joining us; the free and the happy. And a big hug to my family for putting up with me!! Xoxo."
"So proud of you, dad," John, who celebrated three years of sobriety in April, wrote. "Love you."
Rob's sobriety journey began on May 10, 1990. According to Variety, The Outsiders alum decided to reach out for help after he missed a call from his mother.
"I wasn't ready until I was ready," he told the magazine for its Recovery issue. "I was ready when one day back in the days of answering machines my mother called me and I could hear her voice on the answering machine. I didn't want to pick up because I was really, really hungover and I didn't want her to know. She was telling me that my grandfather, who I loved, was in critical condition in the hospital and she needed my help. And I didn't pick up. My thought process in that moment was 'I need to drink a half a bottle of tequila right now so I can go to sleep so I can wake up so I can pick up this phone.'"
Rob called a counselor the next day and soon started treatment and therapy.
"All of my understanding about life has come from getting sober and being in recovery," he said. "The work that you do once you stop whatever it is you've been abusing—that's when the real work begins. And that continues to this day. In many ways, it doesn't get any easier but it does get more fulfilling."
Today, Rob continues to share his experience to help people battling with substance abuse. "Everyone at some point has to come to terms with their own relationship with drugs and alcohol," he told People in 2015. "I have learned a few things over the years. Whenever I have an opportunity to share that with people, it's very fulfilling to do it."
