If your answer is more than “one”, it usually means you don’t have the right pillow for your sleeping position. I have broad shoulders and I was a side sleeper. I used two pillows for the longest time, otherwise I had to twist my shoulder in while sleeping, or tilt my head towards the bed, neither being really comfortable for long time periods. Then I bought a thick foam one on sale in some random store I was at, and it made a world of a difference.
I would use only one if I could find one I like that is thick enough. For a while I put two in one pillow case but the result was too oval in side profile.

That’s the only correct answer.
