ME TOO!!!
I have battled the PND for years.I have to be really careful not to catch a cold because it can last months and months due to the wonderful enviroment my PND has provided.
I would agree that psuedoephidrine is great for drying up and alleviating cough but now available only on script.
The TCM equivalent is Ephedra.I have also had some success with clearing the sinuses with acupuncture.
It is also definitly worth stopping both dairy and gluten products in the diet .This has to be done seperately to ascertain if either or both are adding to the formation of mucus.In me it is definately gluten-mostly in wheat products.
I don't go without all the time(which I probably should).Just when the PND is unbearable.The HIT-sinus connection is interesting.Do you ever notice the drip is actually worse AFTER the antibiotics?
I also have the clearing throat -coughing thing after eating.I was beginning to wonder if I had a fistula.
I am completely over all the drug therapy and I have had success with herbal preparations.I am about to embark on trying to control the inflammation with either western herbs or TCM.Let you know how I go.In the meantime try the food elimination.Might help
