I'm on day 4 of gastroenteritis, likely the result of eating warmed up rice. Since Sunday i've only managed to eat 4 bananas and one portion of porridge. I feel completely wiped out and the heat isn't helping. What can I do to get better? The doctor said they would see me after 5 days, if no improvement. I've hardly eaten anything but am managing sips of lucozade. Every time i've tried eating something i have horrendous diarrhoea within about 2 hours. I also feel nauseous (but haven't vomited) and my stomach hurts and cramps but that's not constant. Does anyone have any suggestions? I am really fed up with it and will try anything!
