"I wanna live my sober life. I don't wanna die. I'm on the verge of dying, because I'm a vicious alcoholic." Tyson said on ESPN's 'Friday Night Fights' following the season finale which was put together by 'Iron' Mike.
Tyson told a news conference, "I'm a bad guy sometimes. I did a lot of bad things, and I want to be forgiven.
"So in order for me to be forgiven, I hope they can forgive me. I wanna change my life, I wanna live a different life now," the former champion said.
Tyson admitted to being a continual substance abuser but was hopeful he was finally becoming clean.
"I haven't drank or took drugs in six days, and for me that's a miracle," he revealed.
"I've been lying to everybody else that think I was sober, but I'm not. This is my sixth day. I'm never gonna use again."
In the main event, Argenis Mendez and Arash Usmanee battled to a 12-round draw at the Turning Stone Resort Casino. Mendez (21-2-1) retained his IBF junior lightweight belt.
Usmanee improved to 20-1-1 in the event, which was titled ''Tyson Is Back,'' and featured some disappointed fans who felt Mendez won the bout. Iron Mike was one of them.
''I'm very grateful,'' Tyson said. ''We had two sensational championship fights. I thought my fighter (Mendez) won his fight. It was a sensational fight, good for boxing, but horrible for my boxer. He's a great boxer.''
Jesus Andres Cueller (23-1) outlasted previously unbeaten Claudio Marrero (14-1) to win the vacant world WBA interim featherweight championship.
