I don't know why, but I've been feeling queasy and I have a lot of saliva everyday. It started half a year ago. I also have constant stomach ache. I've seen many doctors and they don't know how to cure me, or rather their cures don't work. I've tried ginger and it makes me even more queasy. I feel most queasy after I eat or drink. I also started having mild diarrhea, but only once a day and my stomach hurts often. I am also very skinny and however much I eat, I can't get fatter. Do you know why?
