1 — interesting question

Is there a more optimal pillow strat?

you must be a back sleeper?

im a stomach sleeper: currently use 3 that touch my body at a time, and a 4th and 5th for when i roll over

1 stays under my feet to keep my injured knee bent
1 for under my stomach so that my body tilts a little bit, putting my neck in a less twisted position (and another for when i roll to the other side)
1 for under my face to support a neutral neck position (and a donut pillow when i roll to the other side so that i don't rest on my fresh ear and eyebrow piercings)

but i wouldn't call it an "optimal strat"

would be an easier life to live if i didn't have obstructive sleep apnea and could sleep on my back

I’m a side sleeper 

I think I just got used to my setup. The additional complexity doesn’t feel worth it for me
