Dehydration: you sound like you might be somewhat dehydrated. This can be due to a virus or any type of infection. Blood loss or excess heat or exercise can also precipitate this. It is less likely due to neurologic or cardiac conditions although possible. If it doesn't resolve soon you should see a health care provider. All the best to you!
