I have been going crazy the last 4-5 months due to nasal congestion and what feels like a thick mucus in the back of my throat, that will not go away...no matter how hard/often I swallow. This is an all day, every day problem. I am so grateful for reading the other postings that state similar situations. I have also seen a huge decline in my sex drive. I was recently at the Dr. and have just put on amoxicillin, thinking it may be some type of atypical sinus infection. Thank God for these postings. Now I know I am not going crazy!
