I'm not one to get allergies, but during the winter months and only at night, my nose gets stuffed up, usually just one side... Why would that happen only during the winter and only at night?
Very good point. Most likely the heat drying out your nasal cavities and lack of moisture in the air. I had this problem last year and a humidifier cleared things up. Also, two hours before bedtime try doing a saline rinse and see if that helps.
If those don't work and its an allergy, I take bromelain, nettle root, and magnesium before bedtime and wake up unclogged.
