Stomach Bug Remedies?

So Tuesday afternoon I started to feel very ill. I was dizzy and nauseous and my body started to ache. I knew right away it was some sort of flu. The dizziness and body aches stopped after 48 hours, but now I'm constantly nauseous. My stomach gurgles and is constantly flipping around. My stool is watery and yellow. I had the stomach bug last year and it had the same symptoms as this. My classes start on Monday morning and I HAVE to be better by Sunday night. If I miss any of this 2 week intro course, I fail the semester. (Sucks ik) any of you lovely ladies have any remedies I can use to help my poor tummy out? I'm desperate at this point. I hate being confined to my bed (as lovely as it sounds sometimes). I feel like a new person every morning but as the day goes on I start to deteriorate. HELP PLEASE.
