Actor Charlie Sheen announced via social media that he is officially one year sober.

The former "Anger Management" star, 53, shared a picture on Twitter Sunday of his Alcoholics Anonymous medallion. The black and gold pendant reads "to thine own self be true," "unity," "recovery" and "service" imprinted on a triangle as well as a No. 1 - marking his first year clean.

"so, THIS happened yesterday! a fabulous moment, in my renewed journey.❤️©️❤️#TotallyFocused," he tweeted.

Back in 2011, he blasted Alcoholics Anonymous for being a "cult."

“I have a disease? “Bullsh*t. I cured it … with my mind,” he said on the on the Alex Jones Show at the time. “I can’t use the word sober because that’s a term from those people, and I have cleansed myself. I have closed my eyes and in a nanosecond, I cured myself from this ridiculous … It’s just the work of sissies. The only thing I’m addicted to right now is winning. You know? This bootleg cult arrogantly referred to as AA now supports a 5 percent success rate. My success rate is 100 percent. Do the math! One of their stupid mottos is ‘Don’t be special, be one of us.’ News flash: I am special and I will never be one of you.”

Sheen revealed back on the Today show in 2015 that he had contracted HIV.

"I have to put a stop to this onslaught, this barrage of attacks, of sub-truths and very harmful stories that are about threatening the health of so many others, which couldn’t be farther from the truth," Sheen told Matt Lauer.
