Hi Gareth,

I have had this for years. I also had tmj and fibromyalgia. It comes with both. I have also heard tho that a virus can cause it. Mine never stops though. It is definately worse at night because it is quiet, I put a filter cleaning machine in my bedroom at night (white noise) to clean the air and to distract me so I can sleep. I guess I have just learned to live with mine. What is odd is that my dad also has it. He is the one who told me that his doctor told him that a virus can cause it. Although, he suffers from anxiety too but not near the degree I do. It does disturb his life as it does mine if you know what I mean.

Bel
