I've had tinnitus for around 5 years and have learnt to live with it, even though some days it screams and thrombus. High-frequency hearing loss due to age is partly the reason I have tinnitus.

Current thinking is that tinnitus is not caused by damaged ear hairs but by a rewiring of the auditory nerves and the limbic system caused my some kind of trauma (loud noises, colds etc). This means the brain needs retraining to understand that tinnitus is not a threat and leads to habituation. Remove the threat and the cause becomes far less noticeable.

I don't do anything different except wear attenuating ear plugs in noisy environments. I eat and drink as before, ignore useless herbal remedies and get on with life. I have occasional bad days, but I'm not being stopped by cowin' tinnitus.
