In an interview with Today’s Matt Lauer that will air on Friday, Charlie Sheen acknowledges “there are portions” of his past “I would have amended a little bit” and insists he’s completely sober and “calmer” these days. When asked by Lauer when was the last time he had a drink or “something more,” Sheen responded, ” I don’t really keep track of the time. It’s been awhile, because I feel like, without getting into my feelings about AA and all that stuff, if you’re walking around hanging on to your time, it’s only a matter of time before it goes, you know?”

Countered Lauer, “But you’re an actor in a business, and you know that producers out there and people who get involved in projects with you want to know, has it been two weeks, has it been two months, are you bankable, are you trustworthy.”

“Yeah of course, yeah, one hundred percent, yeah,” Sheen replied. “I guess I would just have to lead by example. Words are only worth so much. It’s the actions and the behavior that matter.”

Sheen seemed to acknowledge that his behavior after his firing from Men got out of control, but he fell short of saying he regretted that volatile period. “It was like being shot out of a cannon into another cannon and then being just shot out of that one. It was like from one moment to the next I didn’t know what was going to happen. It was pretty exciting …. I don’t believe in fear and defeat is not an option and I had to live by those mottos. Regardless of how I felt. But yeah, looking back on it, I don’t think I would trade it, but there are portions of it I would have amended a little bit.”

The actor — who was the subject of a Comedy Central roast last weekend and is currently developing a comedy called Anger Management — said his emotional state now is “a lot calmer. It’s a lot mellower … I’m seeing my kids a lot more, mending fences with Denise and Brooke, just trying to move forward and prioritize what matters. You know, just really get back in touch with some more reality and some more. It’s what I call the moments inside the moments. I think that’s where the life is, you know, it’s in those quiet moments. It’s not the giant TV deal or the big party or the award or whatever, it’s the memory of your child’s smile at the end of the day that sort of brings that one lonesome tear, you know that tear, right Matt?”
