Mike Tyson appears to be fighting for his life.
The 47-year-old told Matt Lauer he has been sober for 12 days. However, every day is a tremendous battle.
"It's a real challenge because...I don't know if I like this sober guy.'' Tyson said in the emotional interview. "It's hard for me to live normal. Straight is hard. Livin' straight life is hard."
