Thanks all so much, all my ailments are a) fixable b) don't hurt much, so I've got it easier than some. It's 830!! I've only just got up!! Life of sybaritic luxury 
Managed to resist the foot-up-nostril classic at 1am, yay. And the old favourite, levering head off pillow with back legs (much panting) at 5am. Suffocation by tail in mouth = 7am successfully averted.
Finally caved in to a sharp right hook in the eye at 830, followed by demolition of a pate and raspy purring.
BRILLIANT SOLUTION re Nurse Lee - I'll ask him on Monday.
