thanks to everyone for your replies. i have asked my doc about environmental things being the cause, he told me that is not a possibility.he said sometimes it can be viral .he really doesnt have much to say about the whole thing , he just keeps telling me to take more inderal, it does stop the passing out, but it does nothing for the nausua and dizziness and brain fog . he diognosed me with ncs but believes me and my daughter have "a ball of things going on" i am not sure he is very knowledgeable with this dissorder ,when i tell him about all the other symptoms i am having he looks confused and replies"i dont know why you are having all these other symptoms"anyone know a good doc in the newark deleware ,elkton maryland area? thanks again good luck to alll of you
