I think I possibly have this disorder- I haven't been diagnosed but I find it impossible to control my urge to eat for any length of time! I find myself unconsciously nibbling- I'm not hungry, in fact I don't even realise I'm doing it most of the time!
I wish I could help or advice you but unfortunately I can't do that- but I can certainly empathize with you!
Please come back & report to us. I will follow your progress with interest! Good luck!
