chlamydia infection
"I took four of the azithromycin pills about an hour ago and had a small meal afterwards. The thing is I've been sitting on the toilet for the past 40 minutes with the worst (my worst) case of diarrhea. Although I do find that taking these are very effective; I'd suggest not eating before taking them in case you might throw them up.. Eating a little bit after is good too to keep away from feeling nauseated and all."
