My MIL seems to believe that whenever you feel somewhat sick, if you take left over antibiotics from someone else's prescription, then you should be all good. I think it's ridiculous. My husband hasn't been feeling that great, most likely a sinus infection, so I told him to just go get a shot at an urgent care and he'll feel better. She then decides to give her input and say "Yeah, just go to the doctor where you'll pay thirty dollars for them to give you the same thing I have." 😑
