I suffered from a kidney infection in November. I was put on antibiotics for 2 weeks. About 2 weeks later i suffered from Bronchitis and again put on antibiotics for a week.

However it has now been over 2 weeks since i first got the Bronchitis and when taking the antibiotics I felt fine but since coming off a few days ago, I am starting to feel achy and tired and chesty again.

My immune system is obviously weaker, what can i do to shake this off and improve my immune system. Should i start taking supplements?

Any advice
