Azithromycin
"Had bronchitis for maybe 2 weeks. At first I thought it was a cold or maybe an allergy. My temp started to move up to 99.6, and then 100+ and finally like 101.7. But the cough was the worst. The weirdest cough I ever had, deep, loud coughs and I'd cough for like 30sec+ or cough and sneeze at the same time. Could not lie down at all or I'd begin coughing (but I'd cough anyway). The doc prescribed Z-pak. About 4 hours after I took it, I could tell the symptoms improving. My temp improved, the cough subsided, too. This is my second day. For me there are no side effects."
