You barely have a fever (above 38 you are considered to have a fever). Checking your temperature every minute isn't a good idea either. Check every other hour or if you start feeling much, much worse. More frequently than that is absolutely not needed.
Also, it sounds more like a regular cold than influenza. I've had influenza, and it strikes you out of the blue with sudden chills, severe headache and muscle pain, high fever, and you feel like you're dying. It's not just "bit of a scratchy throat and light fever and I'm well enough to worry".
What you need is fluids (hot water with lemon, ginger and honey is good) and rest, not zofran. You might get some mild nausea, that's normal, but it won't make you vomit.
