I went to Columbia University because they were doing a study on people who suffered from panic attacks, and because I suffered from panic attacks my whole life, I decided to be a part of it. They had this questionnaire where they asked, How many units of alcohol do you have in a month? The top answer was 40 or more, and I got really scared because I was having on average 60 or 70 drinks a week. And I realized that that was a bad sign.
