Counting down to taper

I have two or three more hard workouts left until I start to taper for the Boston Marathon (April 18). I have always found these last few weeks before the marathon the toughest and the most likely time to get hurt or lose focus. Usually, I am feeling physically and emotionally fatigued from all of the long runs and workouts, but this time I feel more refreshed having taken some time off - both planned and forced.
