Zinc, fresh air, and chicken garlic soup....
Cook yourself some chicken soup, open all windows an let some fresh air in, clean up all used tissues and set yourself up in front of the tv or bed make sure everything around you is tidy so you don't feel like you're living in filth. Have some tissues next to you, eat lots and Lots of chicken soup, have a hot shower, get into bed and watch tv or movies all day and you will feel beta in no time
You could also have a sauna these help sweat it out and keep your fluids up (water is best)
You might not remember it but you'll sweat it out.
Are you sure it's the flu and not pneumonia? It's going around.
If it is accompanied by a weird cough, get to the doctor. My grandson just got over it and my neighbor and her grandson had it a month ago. It's contagious so don't take a chance. Better safe than sorry.
Get to the doctor or an immediate care center. They'll give you an antibiotic. Otherwise you end up in the hospital. Don't waste time.
