I have been experiencing constant light headedness, or a constant dizzy feeling for the last week now. I don't know what is going on. The first day it started I thought I had just drank too much coffee, then the next day I only drank one cup and it continued. I have been exercising more in hopes that it will help, however nothing seems to improve it. I knit it is not vertigo, and I have done research and cannot find others with the same problem, until this thread. Please let me know if anyone finds out something.
