chlamydia infection
"Took 2 500 mg pills of this medication around 10pm. Soon after I had very bad stomach pains. Slight nausea, felt very ill. Was super sluggish, and a weird headache. Couldn't get to sleep until about 430am. Then I woke up with a swollen, sore throat that lasted pretty much all day, feeling similar to Strep. Stomach pains & nausea were gone though. Vaginal discharge & smell have pretty much subsided, so I would think it's working. Guess you just have to rough the side effects."
