For achiness, fever or a headache, take some aspirin or paracetamol.
Drink at least 8fl oz/225ml of fluids every 2 hours to prevent dehydration from fever. Dilute apple juice or flat ginger ale with water. Avoid citrus fruit juices if you feel nauseous and milk if you are vomiting or have diarrhoea.
Don't starve a fever. Eat small, bland meals - cottage cheese, yoghurt, bananas, dry toast, baked or boiled potatoes. Don't worry if you're not hungry for 3 or 4 days, but when your appetite returns, get back onto a balanced diet as soon as you can.
If you have a sore throat, gargle with salt water or suck lozenges.
For a runny nose, sip hot tea sweetened with a bit of honey and take a decongestant if you wish.
For a dry cough, use a humidifier and suck cough drops.
Stay in bed - or at the very least reduce physical activity- as long as you can (at least until your temperature returns to normal); resuming your regular activities too soon will encourage a relapse.
Don't drive; flu impairs reaction time almost six times as much as moderate alcohol intake.
Make sure that you see a doctor if you're over 65; if you have a chronic disease; if you feel especially ill or the fever lasts more than 4 days; or if your fever is accompanied by a stiff neck, severe headaches, irritability and confusion
