yes me too. I work in the NHS where they are careful about such things (at least where I work). I was banned from work until 48 hours after last attack, sent to the doc and had to provide a sample for analysis (Iknow, way too much information) the sample came back negative for campylobacter, norwalk and clos. difficile and I wasn't particularly ill with it, just really tired. It resolved over the third week and I was passed fit to work again by the doc who said that likely it had been a passing bug picked up at work and I shouldn't worry unless it happened again, which it didn't.
