I am confident I can solve your pillow problem! I had the same issues, and tons of neck pain for years. Now I use a Mediflow Water Pillow. They’re not cheap - like eighty bucks - but they last forever. One side is memory foam, so you have that comfort and support. The other side is a chamber you fill up with water. Hear me out - you can add as much or as little as you want, so you can make it entirely specific and exact to how you like to sleep. Side, back, both, you can add or take water out until it’s perfect! After a few nights of fussing with the water amount, I’ve not had to touch it for years. Seriously, this is the pillow!
Make sure to follow directions for sealing it, too, and then you won’t hear or have any sloshing sensations when you lay on the foam side. It also doesn’t get super hot at night because the water absorbs a lot of heat. I’ve never had it leak or be problematic at all. My only issue ever is how heavy the pillow is! Water weighs a lot, who would have thought. But that also means the pillow doesn’t wander around the bed at night, in case that was ever an issue.
I hope you try it out! Or find another perfect pillow for your needs. :)
As a fellow GF human because of a colitis condition, the LMNT works well for me. I usually mix it with 2-3x the water recommendation to chill out the taste a bit, but it works wonders. My whole family has a genetic issue that leaves us super vulnerable to dehydration, but I can’t stand chugging so much sugar all the time from other “sports” drinks. LMNT and just DIY electrolyte drinks (water, salt, lemon) have helped a lot.
