Hello,

I had a gastroenteritis (may have been viral or bacterial) from Thursday until Saturday. I started with feeling a bit nauseous on Thursday afternoon, woke up with slight stomach cramps through the night, on Friday I realized I had absolutely no appetite whatsoever, then suffered waves of nausea (felt very very different to anxiety-induced nausea) and then had liquid/watery d* with cramps. I took an anti-emetic medicine and didn't v*. I guess the point at which I may have thrown up would be about the same time as the d* as that's when I felt most nauseated. In which case- lack of appetite, slight stomach cramps and waves of intense nausea would be the precursors an hour before.

That said- I have had similar symptoms to these "precursors" many many times before and not developed a SV!
