Does anyone know if increased catarrh while eating is a PD problem? I also have a cough on waking and post-nasal drip. Hub is getting very annoyed with me coughing through a meal and also clearing my throat. This also happens if I talk for more than a few minutes. Swallowing anythng dry is also becoming a problem. Is this a PD thing or should I just see the GP (don't have a nominated GP in our practice at the moment).
