I have a bad neck and for years used a buckwheat hull pillow. However I ordered a new one and it has less stuff in it than my old one, so I am sending it back. Can anyone recommend a good pillow for the neck? I even tried one of those pillows with the stuff the astronauts use and they make toppers out of, but it is too flat for me. HELP! I am waking up with the worst neck/head pain.
