The 46-year-old actor - who was fired form `Two and a Half Men` last year because of his erratic behaviour and excessive partying - insists he plans to be "mellower" and has turned his back on his wild ways.
He said: "I`m not crazy anymore. That was an episode. I`m a different person than I was yesterday. Let`s just say I have a mellower plan."
During his period of bizarre behaviour, Charlie became famous for over-using phrases such as "tigerblood" and "winning" but he now finds it strange when people shout these catchphrases to him.
He said: "I find it really strange now when someone comes up to me in the supermarket and says, `Winning!` "
Charlie can next be seen in new TV show `Anger Management` - in which he plays a therapist - and says he already "researched" the role because he has undergone similar therapy in the past.
He said: "I spent a year in anger management, so I already did my research."
The `actor` signed up for `Anger Management` because he wanted a happy ending to his TV career following his departure from `Two and a Half Men`.
He said: "I just didn`t want `Two and a Half Men` to be my television legacy. I wanted to do something that ended better."
