Charlie Sheen doesn't "recognize parts" of himself when he looks back on his "cringeable" behavior last year.

The 46-year-old actor - who suffered drug and alcohol problems in 2011 before being axed from Two and a Half Men after launching a number of rants at creator Chuck Lorre - has apologized to the American public for his actions last year, and he has compared his wild behavior to having an out-of-body experience: "I didn't recognize parts of who that guy was. I just wish it was somebody else's body. You say it's been a year - it's either been a day, or a hundred years. I guess the plan was to reintroduce myself to America and to the media and say, 'Sorry about that, but here's what's happening now.'"

Charlie joked it was a "team effort" that led to him ultimately overcome his drug and alcohol issues, but admitted he didn't have many friends through his troubled time. "It was a team effort that was ultimately led by myself. There were not a lot of people close by saying, 'Dude, let's just take a step back.'"

Charlie admits he did feel a "a little bit" bitter about Ashton Kutcher replacing him on Two and a Half Men, but he has got over it by creating new sitcom Anger Management, in which he will play a therapist, because he didn't want his TV legacy to be remembered for the wrong reasons.

When asked if he had bad feelings towards Two and a Half Men and Ashton, he added to the Today show, "A little bit. I gotta work through that. I could probably do it in group on my show. Just not out loud. I couldn't have the Two and a Half Men thing be my television legacy. I couldn't have that end on that note. If this is going to be a swansong, then it's got to be a beautiful experience, and, so far, eight days there was more fun than eight years."
