Update: Six weeks on a suspected candida plan, mouth signs improved but my gut is still weird

Quick update to my earlier posts about gut chaos - constipation, reflux/gastritis, and weird food reactions. I started thinking candida might be part of the picture because I kept getting a white coating on my tongue, sore corners of the mouth, and a yeasty taste or breath that flared after higher sugar days.

About six weeks ago I tried a very basic approach: cut obvious sugar and alcohol, reduce refined carbs, keep meals simple, and add a few over-the-counter things people mention here (I won't name brands). I also got more consistent about brushing my tongue and stopped grazing all day.

What changed: the tongue coating is much less and the mouth irritation is almost gone. My reflux is a bit better too, probably from eating less junk and not snacking late. So I do feel like something shifted.

What did not change or got worse: stools are still unpredictable. I'll be constipated for a couple days, then get urgency and loose stools. Bloating is still a thing, especially in the afternoon. I also get episodes where I feel kind of wired and itchy after eating, which makes me wonder if histamine intolerance is flaring up.

I'm trying to figure out the next step without turning this into a never-ending elimination diet. For anyone who has been in this spot, how did you tell if you were actually improving versus just temporarily removing triggers? Did treating suspected candida make other issues like SIBO, bile problems, low stomach acid, or histamine intolerance more obvious?

Not looking for a diagnosis, just real-world experiences on how you evaluated progress and what you did next.
