Initially I cut out caffeine, alcohol and spicy foods.I started taking magnesium, zinc, gingko, and various other homeopathic and herbal things including Goldenseal(yuk).
I then stopped flying, socialising,exercising, driving and avoided silent or very noisy places.
DEPRESSION big time.
Then I took a look at where I was...the darkest place I could ever be. I thought....Am I magnesium, zinc, selenium etc deficient? Answer....probably yes by then as I had virtually quit eating, but usually no.. Do I feel better as a result of the changes?....most of which happened spontaneously and due to the worsening depression......no, life totally not worth living and tinnitus as loud/louder than ever.
So, for once I took the advice of others....and started the anti-depressants.
Now (and 6 months on) I eat hot curries, drink alcohol and have LOTS of caffeine. I've largely ditched the supplements, eat well and sleep without maskers.
I started to drive, socialise and go out to events (even loud ones....plus ear plugs) and am soon to hop back on a plane.
Tinnitus just as loud, but MUCH less intrusive
Success for me was accepting I had tinnitus which had caused me to become very depressed. I was not taking a deficient diet, wasn't doing anything to cause/exacerbate it, and wasn't to blame for it.
Essentially old life back (plus tinnitus) rather than tinnitus being the whole of my life.
