Yes headaches, but they went away after a few days. Less hunger, more quality sleep (a blessing). A little afternoon tiredness. I start tapering another 2.5mg today. Hoping my moon face will actually start to go back to my normal face eventually, but the huge deal is the pain not returning...so we shall see. Prednisone gave me my life back, but it's not a great thing over the long haul. Best of luck to you. Your body should adjust.
