I've just woken up again with an achey neck and upper back, and I think it's because my pillows aren't supporting my head properly.
But I've tried THREE different kinds - including a very expensive memory foam one 
So can I have your pillow recommendations, please? I tend to sleep on my side or on my front (which might be part of the problem, actually, give that front-sleeping means you're twisting your head to the side quite a lot . . . )
