I was going to say Jack Daniels.Southern Comfort and Amaretto.
Lots of water and sleep.
I also use ibuprofen. I use the bottle thing that you squeeze made by sinus med (I think), it works like a charm. Maybe because of the way the water shoots up your nose lol. If I'm congested in use it twice a day and it really helps.
If you want immediate nasal congestion relief, you can use Afrin. You spray once in each nostril and you will immediately be able to breathe. However, and this is a serious warning, you must absolutely follow the instructions about when to use it, AND you must get off the product by the end of the 3rd day of use.
Yep, Afrin is great when your cold is peaking and you can't breathe at all when trying to sleep. Usually, the 3 days of Afrin gets me through that worst part.
1/8 to 1/4 tsp of powdered Vit C in warm water several times a day. Usually knocks it out overnight.
