Azithromycin
"A pretty positive experience overall if you can get past the whole "crap, I have chlamydia" feelings. Bodies are weird. I've had symptoms for months but my tests have never been positive for it which is kind of scary. What is not scary however, is knowing that this is totally treatable and I'll feel better almost immediately. I took 4 rather large pills right after eating a PB&J, had some popcorn a couple hours later and went to bed. Woke up with some pretty bad nausea and diarrhea. After all of that  things are back to normal."
