Just as a possible point of interest here; I am prone to sinus headaches, especially in the spring and fall, when the weather changes. If you look at the ingredients of sinus headache medications, you’ll see caffeine there. I have discovered that if I take one half of a caffeine tablet(about 100 mg) when I feel one coming on, it disappears and doesn’t come back the rest of the day, most of the time.
