Do not stop taking the antibiotics unless your doctor specifically says to. They don't make you feel better, because thats not what they do. They help kill bacterial infections, and most of the symptoms you get when you are sick are what it feels like when you body tries to kill an infection. If after 10 days you see no real improvement, then it rules out a bacterial infection and means you have a viral infection. And theres nothing you can do about a viral infection, since we have no reliable cures for the flu and related viruses.
So unless you start doing even worse, wait the ten days and finish the antibiotics before calling them back. antibiotics take days to really get working, so be patient and remember: The symptoms you feel are not caused by the infection, they are caused by your body fighting it. And it doesnt take any chances. It'll stay like this until its sure the threat is gone.
