Well I just found out what's wrong with me today actually, i've been dealing with the black outs for about 2 and half years now and i've taken test after test and no one ever had an answer for me until today i blackout at work, i felt it coming on because after dealing with it for so long i new that later on the feeling should subside. Well not to my surpise it didn't i soon after found myself in a chair not remembering how exactly i got there and being put on a stretcher on my way to the hospital. I'm only 20 yrs old so i just couldn't think that anything was really wrong with me the EMT's seemed to be more concerned than i was me BP was 50 points lower than normal they couldn't get a steady pulse, so at that point is when i became worried i was given 1000ML of sodium chloride through an IV, but i thank god for an answer because i didn't like the fact that i was blacking out and sick and i was always told that i was i fine but i'm happy to know that also that plenty of other people suffer from the same disorder, and i would be happy to talk to anyone who reads this and maybe feels an connection to my story because i think it's nice to know that your not alone, because while reading the symptoms I said i have that etc. and it was a peaceful feeling to finaly have answers, and also to know that with a little lifestyle change i can live a full and healthy life.
