Sheen spoke with ABC's Andrea Canning Monday morning on "Good Morning America" about his increasingly erratic behavior. He also spoke candidly about his heavy drug use.

Charlie Sheen said, "Yeah, I am on a drug. It's called Charlie Sheen! It's not available, because if you try it once, you will die. Your face will melt off and your children will weep over your exploded body."

In a statement, Stan Rosenfield said he was resigning as Sheen's long-time publicist. And the actor says he plans to sue CBS for shutting down his hit TV series.
