chlamydia infection
"Wow took 2 500mg an hour ago and started getting nauseous 30 mins later. Just threw up my dinner but feel a little better. Worst stomach pain I have ever experienced. Medication usually never affects me but this stuff is no joke. I've learned my lesson, time to clean up my act I never want to go through this again. Obviously if it gets rid of it.. It's worth it. Good luck to you."
