I stayed up working too late in our conservatory last night–until 1.30 (crazy!!, writing, blogging, thinking, reading French).
It was 32 during the day, then precipitiously dropped. I got a terrible cold sitting in the suddenly chilly room working, and went to bed in a cloud and flurry of sneezes.
Took Night Nurse and sudafed. Slept soundly and woke up well.
Colds, I have convinced, have an emotional as well as an immunological element, and the sooner one can zap them, the better. I am a great believer in Sudafed which masks symptoms and so makes you feel a whole lot better–and this helps your immune system fight back!
