I am somewhat on the mend, and consider myself upgraded to merely wretched and largely incapacitated. Which trust me, is a substantial improvement over recent days.
On the very down side,
I for one blame New Zealand's national fetish for unheated bathrooms and bedrooms . Breathing cold, damp air all night makes it really hard for me, at least, to stay ahead of this kind of respiratory infection once it starts to set in.
