To save himself and his 17-year marriage, Williams entered a 30-day program at the Hazelden Springbrook alcohol rehab facility in Newberg, OR., on July 11.
"My drink of choice was vodka," he told a pal.
"I would buy two pints at a time, one for each jacket pocket. But I had to be careful. I didn't want to be seen buying liquor every day."
Williams told a souce that he hatched a plan to buy booze only at liquor stores owned by Asians, figuring he wouldn't be recognized. He was wrong.
The first time he went into an Asian-owned liquor store, the proprietor said: "Robin Williams, how are you? You buy liquor?"
