Mike "The Situation" Sorrentino celebrated 28 months of sobriety on Instagram alongside a photo of a commemorative coin.
"We Do Recover," he continued.
Sorrentino, who stars in MTV's newest version of "Jersey Shore" titled "Jersey Shore: Family Vacation," has been seen on the show avoiding drugs and alcohol.
Sorrentino recently became engaged to his longtime girlfriend Lauren Pesce in April.
The couple called things off before Sorrentino started filming the series but got back together when it first came to a close in 2012.
"Definitely, she is the one, for sure," Sorrentino said recently during an interview with Entertainment Tonight.
