bronchitis
"In the last year I have had bad coughing episodes on two separate occasions.  One in February and one now in October.  In both instances, the doctor prescribed a 5-day supply of Z-pack and in both cases I had to try to get a second 5-day supply because the first didn't work.  Now I have been through two 5-day supplies and still have a bad cough. I have always had bronchitis problems but it would be a once-a-year event and once I went to the doctor, he would prescribed something and then I'll be better in a couple of days.  I have moved and now I go to a different doctor who seems to be in love with Z-pack.  My first experience with it was after I moved here.  It doesn't work for me."
