The above quote is from John Daly and is inESPN Magazine on page 62 of the June 19, 2006 edition. 

A good example of Daly’s challenge is that in 2005 after coming in second behind Tiger Woods at WGC-AmEx Championship in San Francisco, Daly ‘celebrated’ by going to Las Vegas and losing $1.65 million in five hours.

According to the article he estimates his currently losses over the last 12 years at between $50-60 million.
