You have at least three events you are obligated to attend before Christmas, you're missing quality time with family and close friends, Aunt Bessie insists on smoking in the guest room and you haven't even started any of your gift shopping. Whoa! Holiday stress can make it difficult to relax and fall asleep at night. Instead of fretting, plan ahead and set some limits so you can get to New Year’s without losing any sleep. Check your calendar to see how much free time you have before accepting invitations so you don’t overbook. Keep a to-do list to stay organized and running efficiently -- scattered details are hard to remember. Assign tasks to your family members to divide and conquer. Have kids? They may like getting their own special to-do list. And before relatives visit, tell them the rules of roost, like smoking is only allowed outside.
