You make an important point about stress and its effects. Yes, I am under a lot of stress, and working myself out from under that is an ongoing challenge. Another commenter in this thread suggested histamine intolerance, and when I asked my doctor about it they said yes it's possible (though rare) and that my symptoms can also be caused by stress and anxiety. While I get to the root of it (possibly some adverse childhood experiences), I've made positive changes, including: -Prioritizing sleep and acting on that to get enough -replacing morning coffee with a tap-cold shower, now a daily habit to stay in until I feel the internal response rush of warmth, and not much longer beyond that- no need to actually cool myself down so much, that I know of (I'm not training for significant cold exposure). -getting outside for regular walks -journaling as a brain dump, and then burning the writing -eating a high-fiber, low-added-sugar diet, mostly fresh plants (I'd include sprouts there, and I've since increased the proportion to about $5/week over the initial $3, wrongly calculated as $0.61) -and being okay with doing nothing else except breathing, just because, and as an intervention if I'm having a troublesome emotional response
