I've had food poisoning twice - both in Perth. The first time was a little gem called Campylobacter. The one saving grace is that there is no vomiting. However, severe stomach cramps, lost 3kgs in 48 hours, dangerously dehydrated, 2 visits to hospital. Pain was up there with gallstones. Second time was a more standard variety of food poisoning, both ends going. Ended up on a drip due to dehydration. Not much fun so I sympathise.
