You should definitely upgrade your pillow.
I finally gave into the “don’t skimp on your mattress” crowd due to a good friend of mine having some sort of weird passion about this issue.
That was about 8years ago.
Two years ago my wife got me a new pillow - best improvement since the not skimping on the mattress move and now I actually bring my pillow when I travel by car.
