I used to have a post on the need for water. Most of the afternoon fatigue 
people feel is mild dehydration. Many times you will mistake thirst for hunger. 
You want "something" - what is it> You eat.
You are thirsty and you drink a soda. That dehydrates you even more. Or coffee 
- a huge dehydrator.
Off my soapbox.
