chlamydia infection
"Took the 2 pink tablets, 500mg each, as one dose and everything was fine. I took a nap and a few hours later woke up sweating & really nauseous. I then began getting really bad cramping...Haven't gone to the bathroom yet but I did yack because the nausea was that bad. I really hope the medicine is still effective even after puking a few hours after taking it. Definitely learned my lesson about unprotected sex!!"
