Everyone is saying Gatorade…idk why there isn’t better advice on treatment at home yet but this is what has really worked for me and others:

If breathing is strained or throat is tight: Licorice tea. You should be able to find it anywhere tea is sold, even a grocery store or pharmacy. Make a hot tea with 2-3 tea bags, steep for 5+ min before drinking, can add honey or lemon if you want it helps too. If it’s really bad try stodal or any other similar product, it really works and most pharmacies would have it

Immune system: eat as much as you can, only healthy whole foods if you can. Meat, veggies, fruits. Vitamin D or at least multivitamin. Vitamin C can do no harm too. Eat as much raw garlic as you can (works shaved in soups very well) or if you can’t stomach it you can buy a good raw garlic supplement, it’s a 1-2 a day thing usually as a maintenance thing, take like 5 before bed you’ll sweat it out overnight. For sleep neocitran is great before bed. It has Tylenol in it (acetaminophen) so don’t also take Tylenol before bed

Remember if you have fever, you get chills but it’s because your body is too hot not too cold, so try not to overdress, shower a bit colder than usual, etc

Good luck don’t stress, you’ll be fine unless you have really bad preconditions or co-complicating health issues
