Is there any way to overcome binge eating without therapy ?

Binging: Eating disorders are serious illnesses, requiring therapy, especially if binging and purging behaviors.

Consider this book: Self awareness is critical. Your question is a first step. Please consider the book by chris fairburn called "overcoming binge eating". I have received many direct positive reviews from patients. Some had tried overeaters anonymous, therapy, and other treatments, but felt this book helped the most.

Binge Eating: People who compulsively overeat, though, may use food as their only way of coping with negative emotions. As a result, they often feel that their eating is out of control. They think about food all the time and feel guilty, ashamed, or depressed after eating. http://www.webmd.com/mental-health/eating-disorders/binge-eating-disorder/features/compulsive-overeating-and-how-to-stop-it
