Thanks, I wasn't confused when he was telling me what happens with NCS. Until I did some research on it myself. LOL The original EP that I had thought the same thing. So I have had 2 Dr's thinking the same thing. This makes me feel better. Smiles I can prevent myself from fainting but I have gotten to the point I couldn't move I was so weak. OCsunshine Yes that did make sense, thank you Mack's Mom I often feel like I'm going to vomit when I feel faint. Glad yur son is doing better on meds. Rachel Thanks for the link I'll have to check it out, I too get lightheaded and lose my vision. I told the Dr that I have to blink my eyes trying to clear them. Lauren My Dr told me that POTS and NCS go hand in hand. Thanks
