EDNOS is all kinds of things. It is nothing specific. It contains traits of various eating disorders and thus is classified 'not otherwise specified' as it cannot be classified either anorexia or bulimia nervosa.
It all depends on how you feel about it, as has been mentioned here, and how you want to approach it. Whether or not you see it as a disorder, an addiction, a crutch, a bad habit, or a behavior, if you want to change it it's going to take some hard work and going beyond just the simple act of eating, overeating, bingeing, purging, restricting, etc.
