"10 years sober today," he wrote. "For a guy that couldn't stop shooting heroin, smoking crack and guzzling booze this is truly a miracle. No matter what you are struggling with today just know that change is possible and you are worth it. You don't have to be perfect. KEEP GOING."

Zac's fiancée, Tayshia Adams, whom he met on their season of "The Bachelorette" together, praised him for the milestone, as she tweeted., "You should be so proud for everything that has transpired as a result of your strength, faith & persistence with your sobriety."

"I know I am," she added, "because it gave me you!"

Other fellow "Bachelor" alums commented too, as Katie Thurston wrote, "Solid decade Zac! Congratulations!!" and Jason Tartick shared, "You're an inspiration man and impacting families and lives day in and day out with the work you're pursuing."

In a January episode of the "Whine Down With Jana Kramer" podcast, Zac revealed his recovery was one of the things that brought him closer to Tayshia.

"She didn't have any direct experience with it, but she definitely had an open mind, and she asked all the right questions and some of the ones you hear early on, like 'Can I drink and then kiss you?'" he recalled. "And I'm like, 'Yeah, you're good.'"

"That was one of the things that I was most attracted to in her is that, not only with me but with a lot of guys there, she was able to take on a lot of s---, hold space for us," he continued. "I definitely noticed that early on with her."
