Music star Elton John discussed his uphill battle with substance abuse and bulimia on Larry King Live in 2002. Bulimia is an eating disorder in which people binge, or uncontrollably consume large amounts of food, and then expel the food by vomiting or using laxatives because they don't want to gain weight. Discussing his substance abuse and bulimia, John said he had been "sober and clean" years. "And it was the best thing I ever did. But, you know, those three words -- I need help. If only I'd said them earlier," John explained.
