How can I make my throat feel back to normal by TOMORROW!?

I've had a ton of nasty sinus drainage since Friday and it has made my throat feel tight, dry, and achy. I've fixed my nose (I'm using Afrin nose spray) and I've been taking a LOT of Benadryl to stop the drainage. I've been drinking hot tea and gargling warm salt water too. Is there anything else I can do to have my voice back and throat feeling as close to normal as possible by tomorrow?
