Jax Taylor has reached a major milestone in his sobriety journey.

Taking to his Instagram handle on Monday, the 46-year-old TV personality revealed that he has been sober for a year and a half.

“This week has been a full circle moment for me,” he began. “Late last summer, I checked myself back into treatment for 90 days to focus on my recovery and mental health. 

"This week, I came back as an alumni for their 5K Run in honor of Mental Health Awareness Month," continued Jax.

The Vanderpump Rules alum added, “This journey hasn’t been easy, but it’s been worth it and I’m very grateful to be celebrating 1.5 years sober this week.”

Along with his note, the TV star shared several images and a video of himself participating in the 5K Run.

After sharing the post, several fellow reality stars rushed to the comment section to congratulate Jax on reaching the milestone.

“Let’s go!! Proud of all the work you’re doing!” Jason Wahler penned.

“Rooting for continued sobriety. Keep going," commented the Bachelor Nation‘s Zac Clark.

Jax recently appeared on the We're Out of Time podcast, where he talked about his sobriety journey.

"I know for a fact — and I know you’re not supposed to say it — but I know for a fact I will not touch drugs and alcohol again. I know that. I have no interest in it. I’m not triggered by it," he said.

"I love going and meeting the guys. My sober friends, I’ve shifted from my drunk friends, now I have a sober group of friends. We have a great time. We go out to dinner," added Jax.
