Thanks, Roger. I appear to be doing just as you describe, and feeling very much better today, with the only lingering frustration that I have lost my taste and smell (despite being accused of never having had the former, and that the latter can only be a good thing.... before Mince beats me to it).
That aside, physically and mentally, I feel pretty much back to normal. Emotionally, I'm less certain. I've spent pretty much three days adopting the Andy Capp position on my sofa watching telly-on-demand. It started with binge-watching 'Little House On The Prairie', until I could take no more, and switched to watching the movies 'The Day After Tomorrow', 'Armageddon' and 'Deep Impact' in quick succession. Amateur psychoanalysts among you, don't hold back....
