sinusitis
"I have had chronic sinusitis for the better part of 10 years now off and on. It really gets bad as spring changes over to summer as well as summer over to fall. I have taken several different antibiotics over the years and the sinusitis keeps coming back stronger the next year. So I just started the 7 day ZPak yesterday for the first time and just took the second days dosage. Much like most of the other reviews on this site, I am experiencing some minor diarrhea as well as flatulence. Which, in my opinion, can be a deadly combination for a new pair of white boxer briefs!  



I have not noticed any other side effect as of yet but again I am only on the second day. I will tell you that I am feeling much livelier right now and gained motivation"
