8w4d stomach flu...

I've had the stomach flu really bad today. Constant vomiting and it doesn't help that I'm extremely sensitive to smells. I haven't been able to keep anything down today at all. I've tried pedialyte, broth, toast, crackers, ice chips.... I throw everything up. At this point I haven't been sick in an hour but I have awful nausea still and I'm concerned about being dehydrated. At this point to get any medical help I would need to go to the hospital and I don't really want to do that unless absolutely necessary. Any advice???
