What causes night time nasal congestion? As soon as my head hits the pillow, I can not breathe through my nose.
During the day I can breathe just fine. At night I get so congested I have to breathe through my mouth and keep waking up to blow my nose. I have tried Claritin, Benadryl, the Neti Pot etc. and nothing seems to help. I don't think it is a sinus infection as it only happens at night. Any ideas or suggestions?
