True, but I have yet to hear any good reason to have a stuffed nose so bad you can't even function or sleep well. Pretty sure that's just the illness helping itself spread.
I don't take meds for fevers, but first thing I do when I'm getting a cold is make sure I still have a box of pseudoephedrene to use. It turns 90% of colds or flus into just a boring few days instead of abject misery.
The other two essentials IMO are an expectorant and a cough suppressant. All separate meds so you can pick and choose (it's also cheaper typically, the boxes of random mixed crap tend to be stupidly expensive).
