I don't know if any of us here can diagnose you... But I'd say that if your eating habits interfere with your ability to function or make you very worried/upset, it is possible you have an ED. You mentioned binging on potato chips... How often do you do that? Does it happen with other food as well?

My advice is simple: if you are concerned about developing an ED go to your doctor. It is also possible that the meds you took or the one you're still taking may have altered your metabolism and this is another reason to talk to your doctor.

Hope this helps... Take care
