How much weight will I gain from this binge today!?

there is no definite answer, ik that its a hard thing to do, but forget about what you ate. when i binge like that i put my i-pod on and run in the treadmill for an hour. trust me it will help you forget about what you ate, and it will help you lose most of the calories you gained today. and when you listen to your i-pod get into the music and just start to think about other things, like guys, holidays, partys etc.
