If you haven’t experienced die-off it could be due to a few reasons/factors. If your diet is not strict then it benefits the yeast. If you still consume starches, sugars, grains, beef, etc. then this will feed the yeast and it won’t die.
Your liver might not be damaged very much so you might not get die-off.
Additionally and very likely, you have something else going on such as high histamine levels, leaky gut (inflammation) not related to candida, thyroid problems, parasite overgrowth, h.pylori overgrowth, sibo overgrowth, etc.
If you’ve been at this for 2 years and aren’t symptom free, I recommend getting a diagnosis via stool testing or blood tests.
