I'm been suffering SO BADLY with nasal congestion for the last month or so. It comes and goes. I noticed that if I drink wine, then overnight and for all of the next day, my congestion goes through the roof - and I am blocked and struggle to breathe - also slightly wheezy. I am now off the wine completely to test my theory, but was curious if anyone had had similar? Also, have noticed I am more sensitive to my dog ( if I cuddle him I can get itchy). But it isn't constant. Mucus (sorry) is completely clear, so deffo no infection.
