Azithromycin
"I remember the nurse telling me over the phone to eat a meal with this pill because it makes you nauseous. The pharmacist also told me to eat with this pill. I had a pretty heavy lunch before taking these pills (2) and two hours later, I was hit with an uncomfortable feeling in my stomach which turned into nausea. I had to call into work to say I was running late simply because I believed I would puke everywhere if I went then. Eat a big meal and take a nap afterwards. it's the only thing that helped."
