I wanted to thank you for your posting the link on labrynthitis. I felt this way last summer for about 8 weeks. I had some, but not all, of the symptoms. I did have the bouncing feet, slight dizziness, fatigue, saw the ground moving, etc. and it was awful! My GP said it was just allergies and gave me tablets but nothing helped. As it wasn't that severe (but giving me a fright) I just went on with my life and it eventually went away.
