sinusitis
"I was prescribed Zithromax for an upper respiratory infection and I did not have such a good experience. The first day I had really bad diarrhea. I couldn't even leave the house. The 2nd day I was overwhelmed with nausea. I took the pill with food and still felt sick to my stomach the entire day and night. Today I have decided the terrible side effects are not worth it, and I'm not going to take the rest of my prescription."
