I often experience nausea and fatigue. After some hours I get some
reflux/heartburn or some kind of "sweet" sensation in my throat as if
some stomach acid came up there but without actual vomiting and without
so much nausea as if it was a real disease. But after I get this my
nausea is temporarily reliefed then coming back later, there can go
days or months and then it happens again.



What is this?
