Actually I don't have a 4x4 either and since I've had Crohn's Disease for 20 years (since I was 9) I have felt exceedingly ill while on my own many a time so kindly don't pass judgement on me with no knowledge of my circumstances. The media has been full of stories about the norovirus, explaining the symptoms and recommending that people stay home and drink fluids rather than spreading it about so you shouldn't be getting an ambulance OR a taxi to take you to hospital with the norovirus because that just means that it spreads further. The ambulance that was called was unneccessary and a waste of resources.
