I have been very, very ill for about 10 days. Self-diagnosis strongly suggests that it was gastroenteritis and it is not something I hope to get again for a long, long time. At one point I almost phoned for an ambulance - and bearing in mind that I haven't visited a doctor for over ten years you can see how serious I thought it was.
Anyway, no ambulance was needed - just many bottles of Lucozade. I am not fully cured but today is the first day I have been able to eat solid food.
I have lost loads of weight (I don't recommend this as a diet plan though!) but the best news is my craving for cigarettes has totally disappeared.
