I'm like you, if it's there it just keeps calling to me and I just keep picking at it. I decided a long time ago that it's better in the trash than on my hips. Don't feel guilty about it. There are times when I just want a little something, a piece of chocolate or some treat, so if I'm craving a candy bar, I throw half (or whatever I don't want) away on the way out of the store because it takes care of mindless eating, and I get just what I wanted and not a morsel more.

Usually I just avoid it don't keep it around, but with a gift, as in your case, giving it away is an excellent idea unless you are going to keep eating it, and then I say either lock it in the trunk of your car, take it to the office/gym NOW, or toss. And when you toss, make sure you open it, dump it and toss the cat's litter on top.
