Thank you everybody for all the kind thoughts and good advice. I have:
*drunk loads of orange juice,
*taken Vitamin C and echinacea
*tried the hot hair dryer treatment - it felt very wierd - but decided the wet socks were a step too far!
*had hot baths with lavender, tea tree, benzoin resin and white thyme essential oils
*drunk hot lemon and honey, both with and without whisky
*stayed in the warm and cancelled all outings
*had spinach and watercress salad for lunch
*been really touched by everyone's kindness and positive thoughts
and I do feel a lot better, but will take your advice too sue11 and continue to stay in the warm and rest up tomorrow.

thank you so much everyone - fingers crossed I will be OK on Monday!
