I haven't bothered with a urine test... I think it would possibly benefit me, but I can tell I have these issues from my response (herx) to sticking antifungals/biofilm busters up my nose. There are many essential oils which have several properties desirable to combatting mold infections in the sinuses. Some even inhibit the release of mycotoxins which may reduce the herx reaction. I may have experienced this with thyme oil (herxed, but only for a couple of hours and then felt pretty good) which supposedly does this, but I need to experiment more.
If you stick stuff up your nose and herx like a motherbrother, it's a sign you can probably trust more than the urine tests (if the criticisms are true). Be warned, these reactions can be severe and take time to manifest. I dread to think how somebody like @Martin aka paused||M.E.
would react given their already severe state. The phrases "biting the bullet" and "grasping the nettle" come to mind, but these are too mild. You'd need to hump the atom bomb.
