Azithromycin
"I took 2 of the pink 500mg pills. I had 2 slices of pizzas about 2 hours prior to taking the medication and I washed them down with iced tea. Right before work, I ate again, chicken nuggets from Burger King. I felt fine until about 4 hours later when this intense wave of nausea came over me while I was working. I also felt very hot. This continued on for the rest of the night. Today, I feel better, just a little abdominal cramping, but nothing that interferes with my day to day activities. For me, the medication wasn't a bad experience. Just a  low price to pay for not using a condom."
