Military Ball tomorrow and I still have a sore throat!

So, I have a sore throat (had it since like Wednesday) and I have my friends military ball to go to tomorrow. I’m getting better, but my voice is still pretty scratchy.
What I’ve done to help:
Sucking on life savours/throat soothers
Gargling with warm salt water
Using a humidifier
Taking Tylonel (I’m not the best speller)
Drinking lots of water and liquids (warm apple juice also)
Using that vapour rub stuff on my chest and feet
I’m probably doing other stuff that I can’t think of right now though.

So what else should I be doing so I can talk with a normal or at least semi normal voice tomorrow?
