Saturday Dilemma

It is 7:40AM and I am deciding if I should go back to bed or get showered to start the day. I have a lunch scheduled at 11:30 with the "beach crowd" and work at 2:00. Should I or shouldn't I skip the luncheon and catch my breath from the whirlwind last 2 days or push ahead and do what I have committed to do. (The decision, as always, seems to be between what I feel like and what I should do.)
