Has anyone had extreme dizziness? Last night from about 7pm on I felt so dizzy. Everytime I moved or stood up I felt like I was on an amusement park ride or something that i was much higher than I actually was. I had a very short night the night before approx. 6 hours of sleep and worked all day, do you think I was just overly tired and that's why I was dizzy? Or do other people get dizzy too?
