I have this pretty bad, to the point where even climbing a few flights of stairs will leave me wasted and feeling like utter shit. It's taken 15 years and 10s of thousands of dollars (with insurance) to figure out that I have Hashimoto's. The treatments can help a little bit, but not much, and no doctor can tell me why. I've read a few books that give some plausible sounding examples, but anytime I've mentioned these to doctors they are dismissive yet can offer zero explanations themselves. There are no shortage of chiropractors and functional medicine practitioners that have very plausible sounding explanations, but no real solutions (I've tried every type of diet-based advice I could and it can sometimes feel like things are improving a little bit, but the super hard diets are not sustainable. I've restricted gluten and dairy as those are the two most suggested things that enflame, and I definitely feel better without those things, but it's really, really hard to eat like they tell you too unless you have a personal chef). If you are having similar, try completely cutting caffeine for a little while. It can be extremely hard when you're already fatigued, but it is like gasoline on the fire for me now.
