Thankyou all so much for all your good wishes and kind thoughts, it's very much appreciated.
I've been in hospital for a few days, unfortunately having had to have surgery for a very badly infected and about-to-butst- gall bladder. Op was difficult and "challenging" but luckily the surgeon didn't tell me that until afterwards!
Anyhow, I'm back home with armfuls of painkillers and a few weeks of good rest ahead of me.
I'll be back later.
