Chrissy Teigen recently took to her Instagram to express her weakness: she hasn't had alcohol in the past 50 days.

The star posted an adorable video of her trying to work out on a yoga mat, a near impossible tease to focus on thanks to her children Luna and Miles Stevens.

Teigen wrote along with the video, "Today is my 50th day sober! It should be almost a year, but I've had a few (wine) hiccups along the way! I don't know if I'll ever drink again, but alcohol does nothing for me anymore. It doesn't make me happy, dance, or relax. I feel bad, go to sleep, and then wake up feeling bad for missing a fun night. I enjoyed it and I thank anyone who can responsibly enjoy it! This week is also day 3 of an unprecedented workout for me.

Teigen first revealed that she was sober in December (opens in new tab), and soon afterwards she took to Instagram Stories to elaborate on why she made this decision (opens in new tab). Pasted on a photo of the book Quit Like a Woman: The Radical Choice to Not Drink in a Culture Obsessed With Alcohol by Holly Whitaker, Teigen said, "My doctor and a friend gave me this book for my birthday a month ago. I've had enough of making a fool of myself in public (I'm still embarrassed). I was tired of drinking all day, feeling like shit by 6:00, and not being able to sleep. [I have been sober ever since. Even if you don't think you're sober, even if you don't want to, this is a great book.
