But her gambling spun out of control: She said she would go days at a time at the tables, not eating or sleeping, brushing her teeth with disposable wipes so she didn't have to leave.

She says her losses totaled nearly $1 million.

Now she's chasing the longest of long shots: a $20 million racketeering lawsuit in federal court against six Atlantic City casinos and one in Las Vegas, claiming they had a duty to notice her compulsive gambling problem and cut her off.

They knew I was going for days without eating or sleeping," Taveras said. "I would pass out at the tables. They had a duty of care to me. Nobody in their right mind would gamble for four or five straight days without sleeping."

Experts say her case will be difficult to prove, but it provides an unusually detailed window into the life of a problem gambler.

"It's like crack, only gambling is worse than crack because it's mental," said Taveras, 37, a New Yorker who now lives in Minnesota. "It creeps up on you, the impulse. It's a sickness."

She lost her law practice, her apartment, her parents' home, and owes the IRS $58,000. She said she even considered swerving into oncoming traffic to kill herself. ....

"How are you supposed to know whether this was a woman who was just having a good time, or had money and was just lonely, as opposed to someone who couldn't control themselves?" he said.

Arnie Wexler, the former head of the Council on Compulsive Gambling of New Jersey, estimates there are 5 million problem gamblers in the United States, with 15 million at risk of becoming compulsive.

"Hers is not a rare case, believe me," said Wexler, who says he had a gambling problem. "This is the most powerful addiction you can have without putting something into your body. You remember your first big win, and you think `Hey, I can do this again; I can get it all back.'"

As a young lawyer, Taveras made a name for herself representing the families of victims of American Airlines Flight 587, which crashed in New York City's borough of Queens in November 2001, killing 265 people.
