My tinnitus is there pretty much all of the time, and then for an hour or so it will disappear.
Over the last year or so I've developed really bad hyperacusis, this coupled with misophonia had made me severely suicidal, I even contacted the local mental health services and autism charities.
I've reduced that by wearing coloured lenses, I had been diagnosed with irlen but I see it as a little bit woo, however the coloured lenses have really worked.
My theory - I have a sensory fuck-it-bucket - I'm bombarded by all this crap every day, and if it overflows I'm under real stress, by reducing overload from other senses my bucket fills much slower, and the sound and tinnitus doesn't seem to affect me so much.
Strange to think that a £16 pair of cheap glasses has saved me.
