How to get rid of a stuffy nose and a sore throat very quickly.

Drinking hot blackcurrant helps! Also holding your face over a bowl of hot (not boiling) water can help unblock your nose. Also, put vapor rub on your pillow before you go asleep but don't smother the pillow or your hair will stink of it! You can also get cold and flu capsules/tablets which help so take one before you go and take some with you, they usually start working after 20 minutes and after you blown your nose the once you don't need to for an hour!

I just got over a really bad cold. I didn't have any money for medicine so I made some chamomile tea and put honey in it. It soothed my throat and stopped my cough. I also used some nasal spray that I got at dollar general a while ago. It worked really well.

With colds the best remedy is sleep and water therapy. Throughout the day, drink lots of fluids (preferably warm) and take in Vit C through citrus fruits or juices and get a whole lot of sleep for that night.
I'm gonna be realistic, it really takes a few days to cure a cold. However the steps i mentioned should lessen your colds and sore throat. Follow this method for another day and you just might be well enough to enjoy your beach vacation the succeeding day.

Steam away stuffiness. For temporary relief, take a hot shower, or put the kettle on for an old-fashioned steam inhalation. Steam helps shrink the swollen mucous membrane and promotes drainage. Add menthol or eucalyptus if you like, but the jury’s still out on whether they help. the cooling sensation of menthol creates the feeling of breathing more easily, even if it doesn’t reduce congestion.
Boil a pot of water, and remove the pot from the stove. Drape a towel over your head, and then lean over the pot. The towel will form a tent over your head and the pot that will concentrate the steam. This should unclog your stuffy nose in about ten or fifteen minutes. But don’t lean your face too close to the hot water, or you might risk scalding your skin. And, if things feel too hot under the towel, let the water cool off for a minute or two.
Drinking fluids like water, tea or juice will thin mucus, which will help alleviate your stuffy nose. But avoid beverages that contain caffeine, because they will only make your stuffy nose worse.
Placing adhesive strips across the bridge of your nose will open up your nasal passages. Breathing strips are especially good for nighttime use.
Get a little exercise if you feel up to it. Exercise acts as a natural decongestant by triggering the release of adrenaline, which narrows swollen blood vessels, including the ones blocking your nose.
