I found out I had Chlamydia and I went in as soon as possible to get it treated. I know exactly who it was from, so therefore I know I didn't have it very long. I went in and got a single dose of azithromycin (the drink medication) and I was fine for most of the day. 14 hours after I took the single dose (about 2 AM), I threw up 3 times. I just want to make sure that it was in my system long enough to keep working? I spoke with a nurse and she told me as long as it was in my system for 2 hours I should be fine. But I am still a little iffy on it. Let me know! Thank you.
