Food poisoning !!!!!!!!!!!!!
It's important to avoid dehydration by drinking plenty of water, even if you can only sip it, as you need to replace any fluids lost through vomiting and diarrhoea.
You should also:
•rest as much as possible
•eat when you feel up to it – sticking to small, light and non-fatty meals at first (bland foods such as toast, crackers, rice and bananas are good choices)
•avoid alcohol, caffeine, fizzy drinks and spicy and fatty foods because they may make you feel worse
Contact your GP if your symptoms are severe or don't start to improve in a few days.
