Getting Through The Work Day

Have you ever noticed that we tend to get extremely tired at about 2 or 3 each day?  I am always struggling to stay awake for the last few hours of my work day.  I think that it could be caused by a lack of energy.  I am going to try a new program that teaches you to eat for energy.  This really sounds exactly what I need.  This will help me to be much more productive in the afternoon.  I want to feel better and to have more energy and I think that a lot of others fell the same way I do.
