Charlie Sheen capped off a day full of candid and explosive interviews with one final stop at 'Piers Morgan Tonight.' "I feel more alive, I feel more focused, I feel more energetic," Sheen told CNN's Morgan. "I'm on a quest to claim absolute victory on every front."

"I'm on a mission right now: It's an operation to right some terrible wrongs," he said. "That's what fuels me, the truth."

But even after making those statements, Sheen seemed to be doing a touch of damage control. Wearing an open-collared shirt and a loose-fitting T-shirt, the 'Two and a Half Men' star appeared more relaxed and subdued than earlier interviews Monday. He even admitted he might have been too brash at times and said some things he regrets.

Sheen confessed he could "sort of understand why" CBS executives felt they had to intervene while also asserting that his private life was his own business.

The actor revealed that he hadn't counted the days since he last did drugs because he simply doesn't see himself as an addict -- instead, he's just someone who lives his life to the fullest. "My motto is to enjoy every moment," he told Morgan.
