this morning, i started to wake up a little bit after taking a dose of vitamin d. i had cut my supplementation of d last year to isolate the source of testosterone and have been mostly inside, with little sun, since october. i bought a bunch when i moved in but hadn't taken any yet. i decided it couldn't hurt and might help. i can't build a causal model, exactly, but i started feeling better within a few hours after the second dose of 1000 iu. considering that i was probably pretty low, it has some scientific basis. it was likely better than a placebo. i'll be going back to regularly taking 1000 iu a night, now.
when i started to wake up, i realized i was on the brink of pneumonia (it hurt to cough) and started aggressively hacking out phlegm to clear my lungs, which also cleared my sinuses. i coughed a frightening amount of yellow phlegm up. when i was done, i began to notice that the tenant above me was clearly chain smoking in the house and the sickness, combined with the heat, was hiding it. while i'm certainly sick with a bacteria or virus, i realized it was the smoke that was making me cough.
that means the stalker is probably upstairs.
i did a handful of things to adjust that, including moving the hvac filter into the bedroom, repeatedly running a dustbuster in several places of the house, vacuuming the floors and running a lot of water, including letting the shower run repeatedly. it seems to have helped dramatically, as well.
i'm confident i'm feeling better and should be able to get back to work in a few days.
