Azithromycin
"I was TERRIFIED after reading all of these reviews. I used to suffer from panic attacks but those under control.....without meds. Anyway, I debated and googled and called my docs office and finally my pharmacy before finally deciding to take them. I needed all my questions answered before doing so. All is good! I ate a carb dense meal, drank approx 1 liter of water and took a probiotic all approx 2 hours before taking the medication....after about an hour I ate a small amount more. I barely felt a thing a slight cramp and maybe a wave of nausea that lasted for about 20 minutes. Nothing too intense, I would say  3 out of a 10 for both. Well I am glad I sucked it up and decided to take the meds to get better!"
