Los Angeles - Charlie Sheen is now "absolutely" sober.
The former Two and a Half Men
star - who has been discovered in a hotel room with a prostitute, wielded a machete
from the top of a building and had two live-in girlfriends in the last year - is now a in a "mellower" state, but does not know exactly how long he has been free of drink and drugs.
Asked if he was sober by The Today Show
's Matt Lauer, Charlie said: "Absolutely. I don't really keep track of the time. It's been a while. Things are a lot calmer. It's a lot mellower."
However, he admits he is unsure of how his state of mind came about, and found the time "pretty exciting
" as he didn't know what he was going to do next.
He said: "I really don't know what happened. It was one of those things where the planets were aligned, perfectly or imperfectly. I said some stuff and then it caught such traction globally and instantly that I couldn't really put out the fire.
"From one moment to the next, I didn't know what was going to happen. It was pretty exciting."
At one point Charlie became famous for drinking a mysterious concoction known as Tiger Blood, and that period is one he admits is "silly".
He added: "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. I don't know, the Tiger Blood thing, it was so silly and people took it so seriously and I figured, alright, I'll continue to give the people what they want, you know?"
