Most the so-called 'triggers' do not actually trigger tinnitus directly. Anything that can increase blood flow through the inner ear (alcohol, Gingko Biloba) or increase anxiety (caffeine) can make the tinnitus perceived as louder temporarily. Spending too much time trying to identify these triggers is a waste of time that you could (and should) spend doing more normal things. Also, loooking for triggers also means you are focussing on the tinnitus, thus making it louder !!
