Oh that sounds miserable well just rest assured it will be over soon. The thing with stomach viruses is they are usually short lived. Give it a day or so. Don't worry so much about not having antiemetics around. I know that is easier said then done but the only way to truly challenge your emet is to not rely on them. You will get through it. The good thing is, there is no nausea. So the chance you will be sick is probably low as I would think if you were you would be feeling it by now. Hang in there, keep yourself hydrated and try and stay as calm as possible.
