I'm just back from a foreign holiday, very nice too. Weather was warm and sunny but not hot.
On the penultimate evening I enjoyed a nice dinner and a couple of glasses of wine, had a good evening, but by the time I got to bed had a terrible headache, aching limbs and awful nausea, although I was never actually sick. Hot and cold flashes.
During the night I woke and realised that although I was still in pain, the nausea had passed, so took some paracetamol and went back to sleep. By morning I felt tired, but a lot better, but when presented with food, which I thought I wanted, found I couldn't eat more than a few mouthfuls. During the afternoon I had a couple of bouts of mild diarrhoea. By evening I felt dreadful again. Not sick but headachy and aching limbs.
Next morning (the day of the flight home) I felt fine, had a beautiful lunch on the beach, handled the flight without needing the loo, although stools still a bit loose, only a couple of times during the day.
Today, day 4, I feel Ok in myself, am eating again, the aching has gone, but I am on the loo constantly, with very liquid, watery stools.
