Charlie Sheen no longer feels drained by his work.

The 46-year-old actor was sacked from his old TV show, 'Two and a Half Men', last year following his erratic behaviour and drug abuse but he insists he is now in a much better place, especially with his new series, 'Anger Management'.

He said: ''This whole thing is like a return to innocence for me. I feel younger. I feel like I'm finally involved with something that is nourishing and not debilitating, not draining.''

After being fired by 'Two and a Half Men' creator Chuck Lorre, Charlie initially slated him at every opportunity he had, but admits he's now learnt that's not a wise idea.

He said: ''I've turned it around where I didn't get fired, I got traded. I've learnt to stick with what you know and don't take your dirty laundry public. Out of respect, keep that s**t under wraps.''

The father-of-five - who was replaced by Ashton Kutcher - says he was determined to get another TV comedy as he didn't want to be remembered for getting sacked because of his crazy lifestyle.

Speaking at a press conference in Beverly Hills, Charlie said: ''My legacy could not be what happened at the end of 'Two and a Half Men'. When it went icky at the end, I couldn't have that be what everybody remembered. I wanted to do something that was more about me, who I was as a person, as an actor, and just something that felt more like a warm hug than a snake bite.''
