Michael J. Fox Reveals Struggles

N E W   Y O R K, April 4 -- Michael J. Fox spent seven years hiding his personal battle with Parkinson's disease. But now the actor-turned-activist reveals what his life was like behind the scenes.

"Once I was diagnosed, I started drinking a different way," he said. "It was probably less drinking — the quantity was down — but the quality was really changed for the worse and it really became hiding."

Fox stopped drinking after his wife, actress Tracy Pollan, helped him realize why he was doing it.

"She was basically saying, 'Is this going to be your reaction to this?' And I sensed that I needed to have a different reaction to it. That this was not the way to deal with this. And so that was 10 years ago and that was the last beverage I had," he said. "It was kind of this weak, watery light beer, too. A bad way to go out, but …"
