I completely symphathise. I suddenly got virtigo after a bout of flu a couple of years ago. For about 2 weeks I got around by desperately clutching onto walls, chairs, railings, etc. This gradually got better, but even 3 months later I was getting occasional spells where everything would suddenly slip sideways. Now I am pretty much completely better, but if I am very tired I can still feel light headed.

Hope you feel better soon.
