rhinitis
"OMG! What a life saver I have had migraines for years and the seem to be sinus related more often then not I wake up in the middle of the night so stuffed up I can't breath and my headache begins, a breath rite helps a little. But I have tried just about everything, Claritin, Allegra, Zyrtec, Advil & Tylenol Sinus, Nasacort, Rhino (something) and many others and nothing worked. The Advil Sinus and the old Tylenol sinus helped a little. My ear nose and throat doctor put me on Singular (pill). I bought this after see the commercials stating it blocks 6 types of allergies. Within in 12 to 24 hours I could tell it was helping by 48 hours it was a like a miracle! The pressure in my head, stuffiness, headaches (that were sinus related went away)"
