Over the last two weeks, my husband, 47 yrs. old, has had several episodes where he suddenly becomes dizzy, instantly turning pale, sweating, and feeling nauseous. A couple times it has taken him hours of lying there to return to normal, closing his eyes because he feels so dizzy when he opens them. One day he slept almost the entire rest of the day. Tonight when it happened again, he actually started vomiting, then he laid down and has been asleep for the last hour and a half, already. I am concerned that this is something more than a random event. Tonight he was just prepping some dinner when it happened, nothing strenuous, not any reason to become ill.
