I often wake up with a sore neck, and sometimes a sore back. This is probably due to a previous job, which involved 10-hours shifts in front of a computer and left me with carpal tunnel syndrome, as well as various other aches and pains. My mattress is fine, and I'm experimenting with various pillow combos, but I was wondering if anyone had tried the ones you see advertised in the Sunday mags with a hollow in the middle, and, if so, whether they are worth the money.
