• Try to give up smoking while you feel ill. If you do give up smoking during the illness, try not to start again.
• Try not to have late nights.
• Try not to have too much alcohol.
• Whilst you may not feel up to vigorous exercise, try taking a daily walk.
• Eat a variety of nourishing foods and ensure that you drink plenty of liquid. If your appetite is poor, meal replacement drinks and milky drinks can provide a nutritious alternative.

If your symptoms persist and you don't start feeling better soon, see your doctor.
