I'm a potato loving FREAK! I baked 2 potatos today thinking that I would eat one for lunch and keep the other for home fries later in the week. SO I ate the first potato, yum delicious and I start thinking hrmm theres another potato out there, I might as well eat it, I mean its only 4 points with some butter. I put it on my plate stuck it in the microwave to heat it back up.
I headed into the living room waiting for the beep. Then I stopped said to myself "you aren't hungry anymore why are you eating the other one?" SO I turned around pulled out some foil tossed the second potato in and put it in the fridge.
Moral of the story, stop think and listen to your body. You might not need that second helping.
