I get a pounding headache and nausea - always ending in vomiting - whenever I bend over and put my head back, i.e. as in looking for something on the bottom shelf of a supermarket, (something I try not to do now, but it s automatic sometimes). After vomiting I feel extremely tired; can sleep for four hours, and feel well again when I wake up. What is going on?
