Sickness

Does anybody know of a good decongestant? I have not breathed through my nose in 4 days and I have to get on a plane again in 2…things I’ve already tried include:

-Claritin 24-Hour
-Claritin 12-Hour
-Sudafed 12-Hour
-Allegra D
-Giant Strawberry Margaritas
-Shopping at H&M
-Sleeping with my head propped up on 2 pillows
-Eating spicy mexican food
