What ever you do DON'T stop taking the antibiotics -Harmless bacteria and fungus live in the body in harmony normally - when you take certain types of antibiotics, and the bacteria are killed, it gives the fungus room to breed and grow more than it would normally, hence you can end up with infections like thrush. If you stop taking the antibiotics, not only would the thing that you're taking the antibiotics for not go away, chances are you won't be able to stop it with an additional course of antibiotics due to them building up resistance. People stopping courses of antibiotics half way through is one of the reasons that antibiotics are becoming less effective!! Pop yourself down to the chemist and grab some canestan (sp?) it'll sort you out in no time.
