I blend a head of kale with water and the concoction and usually drink it at lunchtime.
It was so long ago that I don't remember what caused it; I have a vague recollection of it starting when I was boxing at a local gym, not getting hit, just hitting a bag with a trainer, but, as I said, so long ago...
There is one thing: normally, when I talk about tinnitus, read about tinnitus, or pay it any amount of attention, it immediately gets louder. This time, taking the concoction, it's staying at a very low volume, very ignorable. That's a first.
