I've been having trouble eating and a queasy stomach?!

Could be something you ate or you could be coming down with something. Just take it easy for a day or two, eat simple foods like soup or chicken and rice. And take some Pepto Bismol, that will coat the stomach and reduce nausea.

Maybe you unknowingly ate or drank something that was bad or that you might be allergic to and this is your body's way of telling you it didn't like it? I don't think this should last more than a couple days unless you keep eating/drinking the irritant.

maybe you have too much acid in your stomach, try taking imodium.if that doesn't work then maybe you need more fiber in your diet
