OK.....so over the last few years I have been taking some meds that are new to me for my CF care. I also had sinus surgery about 2 years ago. Anyway, I was lamenting the fact that I have lost a lot of my focus......seems to be more difficult to stay on task....not forget things.....complete a project....you know that kind of thing. I have also been getting late morning and mid afternoon headaches that I attributed to sinus problems and who knows what else. My ENT actually did a sinus scan to check out what was going on and thought another surgery may be in the works soon, ughh! Well, for totally unrelated reasons I gave up decaf coffee for the last 2 weeks and I have had NO NOT ONE headache and my focus is almost crystal clear compared to my usual. I am attributing that completely to stopping drinking coffee even though my reasons for stopping it were totally unrelated to how I was feeling and I didn't think in a million years that would have been the cause. Am I crazy or am I on to something.
