How many pillows do you sleep with, how do you use them & which can't you do without?

I use three pillows. I have C-Spine Disc Disease so sleeping in the right position is essential to prevent pain. I have asthma which prevents me from sleeping on my back. I need to sleep on my side. I am fairly wide across the shoulders. Archers might recognize a 40 inch draw as evidence of that. So, three pillows places my neck parallel to my spine while sleeping.
