what kind of pillow should I get?

I need a new pillow. It seems every pillow I’ve ever had hurts my neck.

I’ve tried memory foam, buckwheat hulls, the V pillow, the U pillow, the pillow with the big dent in the center, down, down substitute, latex, fake latex, the water pillow, the neck pillow, the Mackenzie pillow and more.

Can anyone recommend a pillow that won’t give me stiff neck in the morning, (and where to get it?)

I don’t know what’s left that I haven’t tried.
