Ditto. Sometimes a hot shower every couple of hours when I’m at the height of my misery.
The people who invented Nyquil deserve the Nobel Prize.
Believe it or not, hot chicken soup works and no one knows why. Just heat up some in a cup and sip away.
In the later stages of recuperation , hot tub plus Scumpups "juice of whiskey’ is good. Obviously amp up the bromine and oxidizer ( in the hot tub )
The Nyquil was the medication that left the “ass end of a rhinoceros” taste in the mouth, not sure why , but Advil PM was great.
Chicken soup is awesome, ramen chicken noodles with some sambal oelek (chilli paste) is a great hot and spicy chicken flavored suitably starchy/comforting thing that balances the simplicity of preparation ( hot water, add packet of vaguely chicken related chemicals, add Sambal, wait ,consume) with the need for something that can blast through the ‘Satan took a glutinous dump in my sinuses’ feeling.
Hot and spicy instant ramen, made up with twice the quantity of water prescribed by the instructions (smash the noodles up before hydrating, so it can be eaten with a spoon). Repeat as often as necessary (and accept a small weight gain).
But really, any kind of soup-like meal that is warm, spicy, salty tends to help me a lot. Not a cure of course, but helps me feel better (mostly by hydration and clearing mucus, I suspect)
Sweats and T-shirt instead of regular clothes? Check.
Bed or couch to lay on? Check.
Cool pillows? Check.
Warm blanket? Check.
TV Remote and TV Guide? Check.
Book? Check.
Hot mugful of Campbell’s Chicken Noodle Soup with most of the noodles and other (solid, foodlike substances) stuff taken out and maybe 1/4 can of the water to dilute it? Check.
Beer? Check.
Tupperware containing extremely cold Dole pineapple chunks in pineapple juice? Check.
Tylenol? Only if Nyquil is unavailable. Check with a caveat - not a good scenario.
Unavailability of Nyquil leading to shit fit by Missy having to take Tylenol instead of the stuff that actually makes me feel better? Check. Etch it in stone.
Closed bedroom door and/or explicit instructions to those around me and the unfailing acquiescence that no one is to bother me for any reason? Check.
I don’t “do” sick very well. I’m a miserable human being when I feel like crap. Yes, more miserable than I usually am on an average day, hard to believe as that may be. 
Lots of tea and other hot beverages.
Lots of spicy hot foods, especially of the mustard/horseradish variety.
Put a big pan of water on the burner, and just let it boil until the windows are dripping (this works better in a small apartment than a big house).
The goal of all of these is to make my runny nose more runny. It sure beats stopping up, and helps keep the infection from moving into the sinuses, which is the worst. A runny nose when we’re sick is part of the body’s response to try to flush out the infection, which we should try to help along.
Also, I rub Vasoline all over the inside of my nostrils, and just below my nose. This doesn’t do anything about the nose-running one way or the other, but makes it a lot more tolerable.
Equal amounts honey, lemon juice, brandy and boiling water, say, half a cup of each. By the time I get to the bottom, I don’t much care how I feel any more.
I do this with a “vapor action menthol eucalyptus” cough drop in my mouth. I swallow some of the dissolved cough drop saliva, breathe in steam, tuck the cough drop in a cheek, cough and spit. Repeat until cough drop is gone, lungs feel clearer, shower is over, whichever comes first.
Lots of fluids. Any and all the fluids you can drink. Rinse those germs out, or drown them!
I’m lucky, I’ve only had the flu once, and that was about 40 years ago. I only catch a cold about every three years. At the first sign of a cold, I start taking a zinc tablet every 12 hours. Zinc is the main ingredient in the OTC medicines that shorten the duration of your cold, it supports the immune system. It can upset the stomach, so take it with a little something to eat. I’ve suggested this to many friends, and they’ve always thanked me later.
My father swore by Vitamin C for not catching a cold in the first place. He took one of the lower dosage tablets twice a day, about 12 hours apart. He didn’t have a cold the last 7 years of his life, so maybe he was on to something!
