Anyone have a suggestion on quickly getting over a cold/the flu?

I am getting sick, I woke up today perfectly fine, and by mid day I felt a bit of the chills and all my muscles/bones started getting kinda sore. I knew what was coming so I got a ton of OJ and some advil. But I’m still getting worse. I have some friends coming into town on Friday so I want to be better enough to go out by then. Anyone have suggestions?
