It happened about a week later in the am, vomitting, etc. Then it happened while driving but not the same, more like a zap
of adrenaline that caused a major headrush and disorientation for a brief moment. Since then, I have had these zaps about 5 or 6 times,all while driving. I have constant head pressure, feeling like I am swaying, going to fall over or sometimes just plain lightheadedness all day sometimes. It has gotten worse, not really worse but more prolonged lately.
