bronchitis
"I have been getting bronchitis almost every year for the last 11 years. The Zpack is what I was given this time and 9 months ago.  For this round I just my day 3 doseage. I started feeling somewhat better yesterday, however I think I overdid it at work. I completely lost my breath and started coughing horribly again to where I had to go outside and sit down for close to 10 minutes to calm everything down and be able to breath. Overall I feel like it is working as long as I take it easy...the only side effects I have had is I'm exhausted no matter how much sleep I get."
