Azithromycin
"So I came positive for chlamydia and I was very nervous I got prescribed 500 mg of azithromycin it says take 2 tablets by mouth so I took it thinking everything was going to be fine.  I took them early in the am and truely falling asleep about an hour later my stomach was making the weirdest cramps ever not sharp pains just felt my stomach was turning I was VERY nauseous I stood over my toilet for about an hour throwing up saliva nothing else but thin clear salaiva now I'm starting to feel much better I think azithromycin will effect everyone in a different way because it is taking away a STD which is a big deal luckily I didn't have any diarrhea and hopefully I start feeling better ."
