posture
I recommend the Gokhale head cushion, seat cushion, and chair cushion. Shop their amazon store:

allergy
Nettles are a wonderful herb and I like to use them in savory soups and dishes like a cooked parsley. I recommend Mountain Rose Herbs, though they are often sold out.
I recommend quercetin supplements taken for a few days to calm down the immune system, and trust the thorne brand:

sleep
I recommend the dream recovery strips to keep the mouth shut, but you can also use surgical tape (might have PFAS etc). I also recommend their blue light glasses for after sunset.

As a cheaper version of a sleep study, if you’re curious if you have sleep apnea or other sleep disorders affecting your jaw and mind and body, I recommend the Oura ring.
