Allergies
I get allergies pretty bad. Every morning, I use a sinus rinse - called NeilMed. You mix water and these saline packets and squirt up your nose. Basically it cleans your sinuses of the allergens that are irritating it. It's natural, so it's not taking more drugs. If I can nap or it's at night, I take Benadryl when they're really bad. Good luck!
