Obligatory "Lol, sure someone with the name InjectXanax totally isn't planning to abuse codeine"

I'm really going through it right now. I have tonsillitis, lung infection causing chest pain, and an impacted wisdom tooth. This has been going on for nearly 2 weeks now and it hurts to breathe, eat, open my mouth, and drink. My doctor is away on vacation, I can't find a single walk in clinic that isn't fully booked everytime I call, and I don't have a dentist or insurance. So I've had to go to the ER with 6 hour wait times only for a doctor to say "Ya, that looks pretty bad and you're clearly in pain. Here's an antibiotic and a 2 day prescription of cough syurp that should help".

I'm so fed up with sitting around for 6 hours every couple days, just to have a 5 minute assessment. Everywhere I've read online says the codeine syurp I've taken is available OTC, but when I called my pharmacist and explained my situation they just say "ya sorry, can't help with that". I don't know what to do. Have the laws changed? Am I sounding suspicious asking for a temporary refill until I can see my doctor? I'm so confused and don't know what to do.
