Any change from normal eating patterns may create digestive difficulties, but very rich foods, alcohol and low-fiber foods can create troublesome constipation. Pass up the cookies. Instead, toss them out or freeze them for an occasional snack. Go for the fruit and vegetables to eat with crackers. Drink plenty of water.
Water is necessary for proper digestion.
Alcohol does not replace water intake, so be sure to drink plenty of water even if indulging in a lake alcoholic new year's toast. Make time for both exercise and relaxation, which help the body recover from seasonal stresses. If there is a serving left of a favorite rich dessert, eat only half of it for a grand finale.
