I'm awake again - at my laptop at barely 5 am.

My nose is blocked,  my eyes are running, I have a small sinus headache.

The fact is, the ventilation in this "maisonette" is awful, although it has taken me a long time to work out that this was causing my sleep problem.  By about 4.30 am, despite a fan, my bedroom appears to run out of air.

This probably sounds ridiculous.  But this flat, the only one on the ground floor, is part (20 flats) of a hillside building designed originally for offices - and, I would guess - air conditioning.  The windows don't open wide and are in the wrong places.

For weeks i have been trying to find a ventilation engineer - although I expect "he" will tell me I need to spend 1000s of $£€.  I'll probably have to buy a portable air con unit, but on the other hand....

This has taken ages to write.  I am going to attempt sleep again.
