If you've ever been confused about the differences between COE and BED, or the different kinds of bulimia, or what differentiates anorexia from bulimia, etc... I suggest you read this article. Everything this person wrote is so true -- and while it doesn't entirely clear up b/ping or purging anorexia vs bulimia, it DOES give what I consider to be a good version of the difference between COE and BED. And it actually clarifies bulimia as a disorder with binging at its core, but with different methods of dealing with the food than those with BED. I, at least, really appreciated the difference... especially since my bulimia has always been more about the binging and not the purging. But I digress.
