Azithromycin
"Found out I have chlamydia through doing a blood test. I wasn't sure what to think although I was having a lot discharge and a bit of cramps.   Anyways the doc gave me 1 single pill. I had taken it on a empty stomach then I got something to eat after. I started feeling a bit sick and wanting to throw up, I though it was because I hadn't eaten when I took it so figured it was the azi pill.  When I got home few mins later my belly started hurting so I was off to the toilet. I really hope it works and clears this up."
