I am feeling really nauseous, like on the verge of throwing up my food weather i have eaten or not and this has been going on the last couple of days. My stool is real yellow and then green and then yellow. I havent been drinking any juice or sport drinks. my stool looks like pouchites but not having pain. just feel real nauseous and very very tried. I cant seem to shake it off. I have had pouchites before so i know what it feels like, I scared something eles is going on but i dont know what.
