Question: is fizzy good when sick?
Answer: 7. Coca-Cola, Pepsi, ginger ale, Lucozade, Sprite and lemonade – can all help with rehydration after sickness and/or diarrhoea. Drink these if you don't have access to water and/or you need a bit of sugar to perk you up. DO let it go flat and/or dilute with water to reduce its gassiness.
