Mike "The Situation" Sorrentino is 33 months sober.
The Jersey Shore star celebrated the major milestone with an Instagram post on Saturday.
"33 Months Clean & Sober #cleanchallenge," he wrote. "Went from running into a wall to down on one knee. We do recover." He also tagged the Discovery Institute—a detox and rehabilitation center in New Jersey.
The post showed how far the reality star has come. One image showed "The Situation" wearing a neck brace from when he rammed his head into a wall during a 2011 episode of Jersey Shore. The other showed the reality star proposing to Lauren Pesce.
His fellow castmates also showed their support for Sorrentino's achievement.
"I am legit crying I'm so proud of you," Snooki commented.
Former co-star Angelina Pivarnick also commented "resilience."
