Luckily his wife, Mariah Carey, whom he also calls his hero, found him on the floor in pain before the situation got out of control. "Two days before New Year's, I started to feel this horrible pain in my back, they did some more test," he says. "They came and told me that my kidneys aren't functioning. Not just one -- not the one that was in pain -- but both of them weren't functioning right. My immune system started to attack my kidneys… And my kidneys pretty much failed."

Luckily he's back to normal. According to MSNBC, he spoke with Howard Stern and said, "I'm good. I'm feeling 100 percent… Because of this situation I know that I don't need to go so hard. It's more about just my way of living. It's really about taking some time."
Perhaps Cannon's 2012 resolution should be to take a much deserved vacation.
