Charlie Sheen has definitely been through a lot in the last decade, and people are still wondering about the reasons behind his questionable behavior.

The 50-year-old actor made a guest appearance on Wednesday’s episode of The Dr. Oz Show where talked about getting fired from Two and a Half Men, his coke-fueled rampage, and his continued tailspin towards HIV.

Sheen was involved in a strange series of outbursts in 2011, in which he claimed to be a “warlock” with “tiger blood” and also popularized the expression, “Duh, winning!” Previously the highest-paid actor on television, he was kicked out of the CBS series and waged a word war against its creator, Chuck Lorre.

“They picked a fight with a warlock,” “You can’t process me with a normal brain” and “I am on a drug. It’s called Charlie Sheen. It’s not available, because if you try it once, you will die.”

The star, who publicly admitted in November of last year that he was HIV-positive, recalled the tumultuous moments of his infamous meltdown and attributed some of it to his use of a topical hormone supplement.

“It was a lot of highs and lows. I was taking a lot of testosterone cream, and I think I went too far with it. It was kind of like a borderline… not a ’roid rage, but a ’roid disengage.”

Needless to say, people were quite confused about whether his bizarre antics were staged or a real psychological problem. He proceeded to go on a nationwide tour called “My Violent Torpedo of Truth/Defeat is Not An Option,” the tickets of which sold out in less than 20 minutes.

Sheen also opened up about his relationships with former wives Denise Richards and Brooke Mueller. Dr. Oz asked him about allegations that he threatened to kill Richards and their daughter.

Richards filed a $1.2 million lawsuit against Charlie Sheen for selling a house that he gave to their daughters as a gift. The actor denied the allegations and thought that the lawsuit was preposterous.

“I’m basically being punished for giving her a house. It doesn’t make any sense,” he said. “My thought was, ‘She’s burning down the bank and then trying to rob it.’”
