I wake up in the morning with an awful bad breath odor that is apparently coming from my sinuses. Throughout the day I sound like I have a cold, but my sinuses are not stuffed, but sounds like it. I have no sinus pressure or annoying congestion. The annoying part is that I have bad breath from this. I am constantly popping mints or gum. I've tried a saline solution and my doctor gave me Nasonex and Allegra to take, but I'm not comfortable taking them because my sinuses are not congested. I'm not having any trouble breathing through my nose. It sounds more like I have a cold, than feeling it. It is mucus caught up in the back of my sinuses. I do cough through the night. Any help you can provide would be appreciate.d
