The Day After Thanksgiving

After spending the day yesterday gorging on turkey, and dressing I had to keep busy today to burn off the calories that I put on so we went to the church and took down the fall decorations, and then I came home and finished decorating the outside of the house for Christmas. We are having some friends over tonight for another Thanksgiving dinner so I'm preparing myself for the food coma that will follow. Is it true that something in turkey makes you sleepy?
