i mean, i always had it a bit, in my yoot i did lots of listening to loud music, so my ears are a bit damaged, was a few times i distinctly remember for days afterwards being weird

but as far as i can tell, tinnitis is made worse than it would otherwise be by things that increase blood pressure in fine capillaries, in general, anything that increases obstruction in the blood makes it worse too, that would include alcohol (it can cause small embolisms to form from the low oxygenation in the small volume of a fine blood vessel) and indeed carbs in general, and having a elevated blood sugar is going to also decrease blood oxygenation and increase the occurrance of these small embolisms

for sure, these artificial sweeteners are bad, and probably also the semi-synthetic starch derivatives like the various kinds of maltodextrin

caffeine also, and anything that messes with your blood/water/salt levels in general, diuretic effect or thirst suppression

and things that decrease it would be cannabis and gingko... cannabis's effect is more indirect, it has beneficial effects on increasing insulin tolerance, lowering fine capillary pressure by dilation of smooth muscle (this is why it increases pulse)

and last point, i've been starting to see more and more research that is showing that one of the key, broad population scale health issues that is likely attributable to increased ingress of solar energy due to the weakening magnetic field, and a general increase of circulatory and blood pressure regulation problems... likely the energy impacts the nervous system and such

that's about as much as i have on the subject at this point...

i also need to cut out the caffeine at some point too, and the alcohol is now on teh list of imperative to stop, smoking cigarettes that's been finished over a year now, never gonna go back to that, it's the worst (yes, i didn't mention, smoking is a major factor in tinnitis)
