Answer :

You do know that the answer to this is talk to your doctor, don’t you? It does sound like it could be related to a drop in blood pressure but it is not normal.. I had some dizziness for a while when shifting position a few monhs ago but that was related to ear problems. There is also a piece in this week’s New York Times Magazine about a woman who fainted every day. It was discovered that her problem was related to narcolepsy. You really need to see your internist.
