I was on Zinc, Niacin, Quercetin, Selenium, Magnesium, Omega 3, Cordiceps, Propolis, Vitamin C and D3, sublingual B12, Biotin, Melatonin, CBD oil, you name it. I was desperate and there was no info back then and the prognosis of PVFS was just too horrid (ME/CFS) for me just to sit around and wait till it magically went away.
I have to say too that thanks to that I can put tinnitus into perspective and as long as I can have the rest of my body's functionality, I'm happy to live with tinnitus for the rest of my life (provided it doesn't get louder)
My sound is a pure tone, the typical ringing you hear after a concert, only a bit louder.
