that used to happen to me for years, until I figured out that the coffee wasn’t giving me the headaches it was a withdrawal symptom from not drinking coffee often enough!
Once I figured out I needed at a minimum 2 cups a day spread out with one in the morning and another near the end of lunch they went away completely.
I also drink my coffee spread throughout the day — about for cups total. Two in the morning, one after lunch, and one around dinner time. If I start to get “that” niggling headache I realize I missed a cup, and head for the Keurig.
I understand it’s my drug of choice. Not proud of it.
