Afternoon. I have just had my 3rd pass over the course of 1.5 years, going back in time, the first episode was on a early morning flight, I may have logged 5 hours max. sleep prior to the 5 hour flight. The 2nd episode came upon me on a late Sunday afternoon prior to my weekly hockey. The third and most significate was this past Friday around 930 am. to which I lost complete consciousness, fell and crack the back of my head requiring several stiches. In all cases, it is initiated with a loss of hearing, sweat like systems and a loss of balance. I am and work in a family owned and operated business to which we have 137 staff, I don t know if its stress related, hearing related, food allergies... please advise your thought by return emal
