Drew Barrymore spoke out about her decision to become sober. 

The 46-year-old talk show host recently revealed she hasn't had alcohol in two and half years. 

"I'm just going to say something for the first time in a long time: I have not had a drink of alcohol in two and a half years. And it was something that I realized just did not serve me in my life," she told the hosts of CBS Morning while promoting an interview she did with Machine Gun Kelly about prioritizing your mental health.

Barrymore also discussed why she chose to seek help after her "painful" 2016 divorce from Will Kopelman and how social media can be a dangerous medium for young girls.

She realized, "We’re in an impasse and a crux of a moment where talking about how we figure ourselves out, how we fix ourselves takes a journey and solutions. Most people do it in private… I wouldn’t be surprised if there is a revolt against the perfection right now that we are all forced to see and feel through social media."

"I see a lot of pictures of me and there’s like, smiles on them," he said. "It’s just weird though because I didn’t feel good at all that day and I kind of am sick of smiling on days when I don’t feel like smiling."

"And I feel like this odd pressure because I don’t want my fans to think that I’m taking something for granted — so if I accept an award and I’m super smiley, but behind the scenes, there was stuff going on…"
