My nose never used to run during or after eating, however for the past few months it runs during almost every meal. I have been cleansing since January. By cleansing I mean liver flushing, parasite cleansing, and keeping a strict diet(little to no Sugar and basically just eating white meat, fish and vegetables). I have to believe that this is part of the cleansing process. Along with this, when I wake up in the morning I have a ton of mucus in my nose that almost always contains what appears to be blood. I attribute this to the cleansing process as well.
