I really enjoy having my morning coffee every day. I found though that any time I wanted to take a short break (for whatever reason) that I would get a really bad headache for a day or so. It almost got to the point that I wanted to quit drinking coffee altogether.
I recently made the decision to switch to only drink decaf. I'm really happy with the decision. I can still enjoy my morning coffee (for the taste) and I don't feel bad if I decide to take a break for a day.
