A difficulty I'm running into with health-logging, which that thread doesn't really address: in my experience, most of my most common symptoms from health issues are ones which differ from day-to-day life in degree, but not in kind. Sneezing more often, or being thirstier, or having less energy, or the like, where my baseline existence already involves nonzero amounts of sneezing and thirst and energy-limitation.

When it comes to things along those lines, how do you (a) notice when they're happening an abnormal amount (which often takes me a couple days, when I get sick), (b) decide when the abnormal amount in question is beyond the cutoff point between "normal unremarkable fluctuation" and "Something Happening", and (c) notice, after a bout of sickness, when the raised levels are gone and things are back in the "normal unremarkable fluctuation" zone? Currently, I struggle with all of those, and it's hindering my attempts at health-logging pretty heavily.

(Also hindering my attempts at health-logging: getting used to things. It's a lot easier to go "there are sores in my mouth being bothersome" two days into having them than two weeks in, because after a while, even if they continue to be bothersome, they're no longer attention-gettingly unusual.)
