I binged on ravioli last night, so you're way better of than me at least!
Just get right back on track and forget about it. And think of this- even if you ate like 4 cups of grapes (which is a LOT of grapes), you're only looking at about 450 calories. For a binge, that's not too bad! Probably the same as ONE piece of cake or pie.
Grapes are sooo yummy though... right when I get home from the store I have to portion them out into one cup portions, so I don't just keep picking on them all day!
