Azithromycin
"Second time having chlamydia and absolutley the last! First time round I suffered from terrible diarrhoea, to the point where I actually couldn't hold it in (how embarrassing). Now it has been around 3 hours and I have a mild stomach ache and I feel sleepy. The drug is effective, as I already know, but the side effects are a pain. Couldn't stress enough to just have protected sex, none of this is worth it and boys can and will lie! Stay safe."
