I am not just talking about that light-headed feeling you get when you stand from leaning over or crouching down, but that feeling of furiously spinning round when you turn, as if you were on good roller coster. When you stop turning, your head carries on going round, sometimes so furiously that you feel nauseous. Occasionally preceeded by a hangover-style headache, which would be ok, except that I haven't had the pleasuer of the drink. And I am too old for roller-coasters.
8 days now, and it's only just beginning to ease off enough for me to write this.
