The past couple days I have been experience an upset stomach and fatigue. My stomach hurts as if I have a strange combination of feeling nauseous, but also hungry at the same time. I don t have a flu, and haven t ha diarrhea or vomiting, although sometimes I feel as though I need to. I feel better after I sleep, but as soon as I eat something the feeling of nausea returns. It almost feels like motion sickness, which I usually don t suffer from and seeing as I m not in the car, I don t see what is causing it. I have been working out regularly and eating healthy as well as drinking plenty of water. No major changes in diet. Any help would be much appreciated!
