Lots of hot fluids, rest, and vapor rub (I used monkey balm because it was around the house but same idea :)
I drank lots of water and rest as much as you can. Veggie soups with brocolli and garlic to boost my immune system. Orange juice. Definitely lots of water and my cold went away. Try Ensure that has Immune system boost on it.
Put some vaporub for your nose it worked for me and drink some tea
Use a sinus rinse and a vaporizer. . Wonderful. ..
I've been taking mucinex and drinking lots of water. It's been working great!
