Help, cutting down on coffee!

Here's the deal: too much coffee is not a good thing! That fresh roasted coffee is soooooo goood, but I found myself drinking way too much.....I am reading "The Core Balance Diet" by Michelle Pick. It is very interesting.....of course she is suggesting perhaps I drink too much coffee...so I'm giving it a whirl. Cutting down to half caf. If you see me sleeping in the pick up line at school.....you'll know why!!! Seriously, with all the training I've been doing for the Avon Walk, it is only logical to me I should consider what fuel I am putting into this body!
