I have a great idea.
Why not eat something rotten? Keep a rotten something like banana or vegetable, as backup, and everytime you feel stressed and want to eat endlessly, eat that rotten something.
This is what I call a miracle comes true. There is a 100% guarantee that you wont grow fatter, you might even lose weight from all the vomitting and diarrhea. In addition to that, you will be so busy rushing to and fro the washroom, or just conveniently slumped in the washroom with pain, that you will forget your misery.
Dont say thanks to me yet.
