Sip this – A rehydration drink, e.g. Dioralyte, £3.75 for six sachets, Boots, to restore lost minerals and salts, plus plenty of water. If you’re really poorly, take a soluble painkiller like aspirin and an antacid, e.g. Setlers, £2.29 for 36 at pharmacies to settle your stomach.
Eat this – A banana or a kiwi to boost the potassium levels in your body that are depleted when you’re dehydrated.
Avoid this – Your usual morning coffee. The caffeine will just dry out your system more, exacerbating your symptoms.
