I too have had a cough and excess phelgm for about 9-10 months. Have tried everything and had all the
usual tests such as chest
x-ray, ct scan, broncoscopy, etc., etc. and have been on all the
usual medicines. I have dis
covered through some research of my own, that white foods (carbos) can cause excess phelgm. If you
will try eliminating or at least cutting down on pasta, potatoes, white bread, white sugar, you
might find it will help eliminate the
phelgm. It has helped me considerably.
