In her memoir “Sister Wife,” available now, Christine opened up about battling an addiction to oxycodone in private.

Christine shared an excerpt of her book with People Magazine, explaining the addiction started after she tore her ACL and meniscus in 2016.

She wrote that she had always been hesitant to take something “that masks the problem,” but after feeling like she “had the flu” while also being “achy from head to toe,” she opted to take the oxycodone and “all the symptoms went away.

“It gave me the best high I ever felt. I was on top of the world, and I could accomplish everything!” she recalled.

When it came time to tackle her addiction, she told People she wanted it “dealt with it privately because at the time, it was absolutely devastating.”

“It was very difficult, and even though I was on it for a month, the effects of it lasted at least six. I didn’t feel normal,” she continued. “I didn’t feel okay for so long. So, once I was done and I felt better, I just felt good to feel better. And I realized that with writing the book, that’s something I didn’t go back and revisit was the addiction to oxycodone.”

Christine acknowledged there is a time and place for the medication.

“If you need it and you’re in a lot of pain, there’s nothing better than that, but since I can get addicted to things easily, it seems it’s just best to stay away from that kind of thing,” she said. “But I just wasn’t in a place where I could talk about it on the show. I just really couldn’t. It was so personal, and it was embarrassing, and I didn’t know if I wanted people to know that about me.”
