Helping yourself get better after being ill with diarrhoea and vomiting:
Make sure you drink plenty of water in the first two days after your illness – aim for 3 litres / 24 hours. Dehydration can make you feel really weak and tired. Dioralyte is useful – it contains the right balance of salts for your body and can really pick you up quickly from dehydration. You can buy Dioralyte at any pharmacy.
Get some energy inside you: (flat) fizzy drinks like lemonade (not the diet kind) are good for this.
If you’re a regular caffeine drinker, you may be withdrawing from caffeine a bit after a day or more of vomiting and reduced intake. “Pro plus” or flat Coke will help you get over this withdrawal feeling.
Use paracetamol (1g up to four times a day) to help relieve any muscular aches and pains or headache. If you have stomach cramps, Buscopan – available at any pharmacy – is really good.
