Same, I've pretty much always just dealt with it myself, when I was really sick my mom would maybe bring dinner to me because I can't get out of bed but that's about it.
What else is there to do anyway?
Well, I do things like drink lots of water, abstain from milk, eat a clove of garlic, intake a bunch of vitamin C, drink some tea, etc.
I already have a strong immune system, so with these extra measures, it's usually it's all gone in a couple to a few days.
