I give up

In an attempt to reset my system, I was cutting back on caffeine. For a few days I haven't made my morning pot of coffee, haven't had my Diet Coke at lunch, haven't taken down half of a 2-liter bottle with dinner. I've only had a few glasses of pop (I don't care what else you may call it) over the past days. But this morning, to get my eyes unglued, I caved. As I type I'm feeling the life come back to me by way of hot black liquid.
