On the sweet/white potato thing: I've discovered a new snack trick for myself. I buy these Sweet Potat-oh!s. They come shrink-wrapped in plastic, and you throw them in the microwave for 7 minutes. It's a great snack with a little fat and salt thrown on, and keeps me out of the Girl Scout cookies.

I also buy bags of sugar snap peas +/- baby carrots, and nosh on those. Fills me up, and keeps me out of whatever else I might grab at the moment. I do not tolerate being hungry very well, and I will eat the wrong stuff if I don't have the right stuff on hand.
