Now, he admits he wishes he had cleaned up his act sooner so he could have enjoyed his early success. In an interview with "Today" host Matt Lauer, he says, "I wasted such a big part of my life. I was a drug addict and self-absorbed. You know, I was having people die right, left, and center around me, friends.

"And yet I didn't stop the life that I had, which is the terrible thing about addiction. It's that -- you know, it's that bad of a disease."
The full interview is set to air on "Today" this week.
