“She wasn’t my final straw—she was my first harvest,” the actor writes in his memoir, also sharing his family’s response to his revealing new documentary.Charlie Sheen is reflecting on the life-changing moment that made him commit to sobriety.

In his newly released memoir, The Book of Sheen, the 60-year-old actor recounts how an encounter with his daughter Sami Sheen inspired him to quit drugs and alcohol after years of struggling with addiction.

The turning point came on the morning of December 10, 2017. By 9 a.m., Sheen had already downed three coffees spiked with whiskey—enough to make him forget he was supposed to pick up Sami, his daughter with ex-wife Denise Richards, from an appointment.

Too intoxicated to drive himself, the Two and a Half Men star asked a friend to take him.

“Sam was very quiet,” Sheen recalls. “I didn’t need to be clairvoyant to know what she was thinking.”

He imagined her questions: “Why isn’t Dad driving—again? Why can’t it be just the two of us like it used to be? When is Dad coming back? I miss him.”Sami is the first of Sheen’s five children. He also shares daughter Lola, 20, with Richards, and is father to 16-year-old twins Max and Bob with ex-wife Brooke Mueller. His oldest daughter, Cassandra Estevez, 41, is from a relationship during his high school years.

Reflecting on that morning with Sami, Sheen writes, “There was only one thing that felt worse than betraying myself—and that was failing my children.”

He continues, “I knew exactly what had to be done. Sami wasn’t my final straw; she was my first harvest.”

The very next day, Sheen took two Valiums and drank three beers—his last use of substances before committing to a sober life, which he has maintained ever since.Sheen has been promoting his memoir, released this Tuesday, along with his new Netflix documentary, aka Charlie Sheen.

At the documentary’s premiere last week, he shared how his family—including his children—responded to the project.

“As any parents would be, there was initial concern,” he told E! News. “Not about how it would be received, but how it might affect me, and whether I was really ready to dive this deep.”

“I told them if I don’t do this, I’ll never control the narrative—or at least influence it, or bring some truth to all the fiction,” he added. “Once they saw I was confident it was the right move at the right time, they were fully supportive.”This openness comes amid ongoing speculation about Sheen’s strained relationship with Sami.

During a recent Good Morning America interview, the Major League star admitted he isn’t sure what led to their estrangement.

“As long as everybody’s still in the game, there’s a chance for a better tomorrow. I honestly don’t know what I did—that’s the issue,” Sheen said. “I don’t know what I should apologize for. But I truly believe this isn’t permanent. We’ll work it out.”

He emphasized that his bond with Sami is “too valuable to lose.”Just two days before the interview aired, however, Sami seemed to mock her father in a TikTok video responding to his People magazine cover.

In the clip, she reacted to a segment where Sheen played “Phone a Friend,” naming who he’d call for a laugh.

“Hmm. I’m gonna say…” Sami paused, then smirked, “anyone but your daughter?” before laughing as the video ended.Earlier this year, viewers got further insight into their relationship on the Bravo reality show Denise Richards and Her Wild Things.

In one episode, Richards tells her daughter Lola, “Your dad wants to have lunch. Sami won’t go because she doesn’t want to. But he wants to see you.”

In a confessional, Sami stated bluntly, “I would rather do literally anything else than have lunch with my father.”

She reflected on her childhood, saying, “It happened in big chunks. The first 13 years were pretty bad. Then we were okay for a while. Now… it’s just whatever.”On Gia Giudice’s Casual Chaos podcast in March, Sami shared more about her experiences growing up:

“For most of my childhood—like the first 13 years—my dad was in and out of my life. The worst was when he’d promise to come to something, then not show up, or arrive 10 hours late. Eventually, we just stopped inviting him.”
