You should have your ears checked. I just remembered this. I used to get dizzy all the time, especially when I was in certain positions. You can have calcium deposits that settle in your middle ear and can make you really dizzy. I went to a doctor (ENT) who set me up for a procedure to correct it. It makes you really dizzy while he's doing it! I felt like I was on some carnival ride! I haven't been dizzy since, which is why I forgot. It's VERY common. Maybe worth a try?
