bronchitis
"Was prescribed this after a 5-day, then a 7-day course of a different antibiotic each time led to bronchial symptoms (with increased body temperatures) never fully going away and strongly reasserting themselves in a few days. The 500mg tablets are a pain to swallow (you need lots of water to flush them all the way down) and, as most respondents report, cause a permanent nasty bitter taste in the mouth. However, by Day 3 I was feeling much better and now mid-way through Day 4 coughing nearly gone and phlegm much reduced. Temperature also back to normal. In short, feel practically ready resume working."
