Hi I also had and still have on occasion the type of tinnitus, pulsating, shrieking, extreme when a sudden noise occurs, and sometimes it is making a white flash of light in my eyes a bit like lightening (when a spoon fell on the floor was the first occasion when this happened. being tired, frustrated or scared/worried do increase the volume, eating too rich a meal does it too as well as drinking any sort of alcohol, one glass of wine can soar the volume, a few drop of liquor do the same, coffee should be decaffeinated and sugar, cakes, and soft drinks will increase the volume somewhat and it is easy to learn what does it as it is almost immediate
So, for me, more veggies than meat, only one egg per week, and drinking a lot of good water. Relaxation can lower the volume of tinnitus, and I am trying to find the "biofeedback" way to control it as I heard 2 years ago a AN patient from Florida tell me. She also told me her brother has cured his high blood pressure with biofeedback. I wish my computer had not crashed a few weeks later, I have lost all addresses.
Good luck
