I have a history of passing out, anywhere, at any time, out of no where. I will all of the sudden go cold and feel very light headed, my eyesight will go black, my ears will get all hot and down I go. Sometimes I am told I wake up right away, other times I am out for longer, and I always vomit each time I come back out of it and feel all tingly and dizzy. Does anybody else do this? It happens to me very often...That I am afraid to be alone as my most recent episode happened while I was driving. I could feel it coming and was able to pull over but...I wish it would stop, I can't seem to control when it shows up.
