I came down with acute Bronchitis 5 weeks ago, my doctor gave me a z-pack antibitoc and an inhaler. 5 weeks later I m still coughing and producing mucus, but the strange thing is ..sometimes it s clear and sometimes it s brown. I am also noticing a strange mettalic taste to it also. I m worried it could turn into pneumonia . I do smoke but have cut back . My friend who used to be a paramedic gave me sterroid antibiotics , and assured me they d work, but they were nt prescribed for me and I m leary about taking them . Should i go back to the doctor tomorrow or just wait it out? any advice would be appreciated.. Thanks, Tony
