The revelation came in reply to an Instagram comment on a video of Chrissy dancing on vacation in St. Barts, which read: "I need whatever drugs you're on!!"
And later, Chrissy shared she had made the decision to quit alcohol after receiving a book about sobriety for her birthday, revealing she was "done with making an ass of [her]self in front of people."
"One month ago, on my birthday, I got this book from my doctor and friend," the model and author wrote in an Instagram story. "I was done with making an ass of myself in front of people (I'm still embarrassed), tired of day drinking and feeling like shit at 6, not being able to sleep."
"I have been sober ever since," she went on.
