It's a "hate to believe it, can't argue with the results." My time off coffee has been a huge eye-opener for me, I'm back to drinking currently, I definitely saw the change to my body and health in my energy levels and focus day-to-day. End of the day I see it as a something I enjoy, if I'm in flow-state I skip it unconsciously, I don't need it, I enjoy it. I don't feel guilty about drinking a cup of coffee anymore. Although much like a beer I'll feel a bit guilty if I have 5-10 cups in a day.
