I woke up this morning and immediately felt sick. I've vomited a few times. I also have diarrhoea cramping. About 2 hours ago, though sitting down, I felt I was going to faint (hearing going funny, sweating, funny feeling in my head), so I lay down for an hour. Seemed a bit better when I got up, had a few bites of toast and a few mouthfuls of tea, then the same about to faint feeling again and I've broken out in a cold sweat. Still feel nauseous.
Any ideas?
