Hi there, I was just diagnosed with gastroenteritis as of yesterday. I have been lightheaded, nauseated, vomitting, and have been fatigued to an extreme degree. I have only gotten Ondansetron as a treatment for nausea. I have had a urine test done, a cbc, and an abdominal ultrasound...all were normal. I work at a veterinary clinic in the housekeeping dept.. How can I get the proper treatment for this ailment?
