Matt Lauer and Charlie Sheen

Charlie Sheen isn't saying sorry for his behavior in the wake of his firing from Two and a Half Men in March, but he does admit he would change "a little bit" if he could in a new interview with Matt Lauer for Today.

"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," he said in the interview, according to Entertainment Weekly. "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."

In the interview, airing Friday, Lauer also asked Sheen when he last had a drink "or something more," to which Sheen responded with no definite answer. "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?"

Lauer then asked Sheen if he was "bankable" and "trusthworthy," saying producers would want to know about his alcohol use. Sheen said he is "one hundred percent" trustworthy. "I guess I would just have to lead by example," he said. "Words are only worth so much. It's the actions and the behavior that matter."

Months after the end of his Men gig, and his subsequent media blitz and "Torpedo of Truth" tour, Sheen told Lauer his emotional state is now "a lot calmer" and said he's working to rebuild his relationships with ex-wives Denise Richards and Brooke Mueller and focusing on his four children. He has two daughters with Richards and twin sons with Mueller.

"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," Sheen said. "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?"
