I disagree. I know someone who has. Although you can say his was an unconventional version of it. He was in finance and gambled through his by impulsively "betting" on the riskiest investments. He realized that the way he operated at work was the same way a guy at the race track would bet on horses and got help at a gambling anonymous group. Basically, he said that he had no motivation to work unless the threat of losing everything was always lingering in the background, but now he no longer works in that manner and has secure investments set up for the rest of his life while still being motivated to work without unnecessary reckless risk. He also said he has been able to settle down, marry and have children since working on his gambling impulses because before he did he could never get married because he was always worried in the back of his mind that "he could do better" so he couldn't commit. I thinkgetting help, which led to him having a family, has helped him with his gambling impulses.
But I do agree it's very difficult for people to kick this addiction and is pretty rare to overcome. But I wouldn't say that people never get over it either.
