I have been taking Zyrtec-D and at first it seemed that was working but now I am having more stuffiness. I can't breath through my nose. I have tried nasal sprays to no avail. I have tried other over the counter meds such as Claritin and Tylenol Sinus but none work. I go to bed at night and I am fine for a bit but always wake up at about 4am. I am exhausted and am not getting enough sleep. Off and on I have been having a little shortness of breath. I am not sure if I am combining too much with that as well. I go off and on because I am worried about using nasal spray too many days in a row. I also am plugged up so much that I can't even blow my nose. Nothing comes out! I can feel it drip though in the back of my nose. I went to the doctor and he was going to put me on a nasal spray but he forgot to. I have been on that same one before however and it didn't do anything. I am thinking of seeing an allergist. Just don't know when I can get in one and where and if they are covered under my insurance. I am just worried about breathing and getting sleep. I am at my wits end! Help!
