I also found that Excedrin was the only thing that would help my morning headaches but only if I took it at the onset. If I waited too long then not so much.
Another thing I discovered on my own that was a major help and possibly the cause of the headaches. I started rolling on my back on a 6-inch foam roller. From the neck down to mid-back. The very first time I heard a few clicks which I assume were vertebra going back in place? The morning headaches are gone.
I still get headaches if I sit at the computer too long or fall asleep in front of the TV. The weight of my head bent forward stresses the muscles up the back of my skull. Apparently, your head weighs the same as a 14 lb bowling ball.
