Do you mean in order to diagnose "binge/purge disorder?"

I googled it. Bulimia is definied as binge/purge, otherwise it's "just" purging disorder. Which, given your previous diagnoses, such as ulcers and your kinky intestine and gallstones(?), may not describe the whole situation. With all the processed food and caffeinated, carbonated drink you pile and pour into your tender overmedicated tummy, i think you invented Munchausens by Junk Food!
