bronchitis
"I took a full course of the 250mg 5 day pack with no ill effects except for a metallic taste in my mouth but then the bronchitis came back, so was prescribed the 500mg 3 day course. On day two, I got severe stomach cramps, diarrhea, and vomiting. I am not going to take the final dose, because although the bronchitis is better, I can't deal with the intense stomach discomfort."
