Hi Dino, I would like to make a suggestion. I am a retired Federal Police Officer and back in the late 1990's, ten of us officers were coming down with a lot of nasal drip which we assumed was stress or allergic reaction to something. After a lot of research, we decided to try "Cleansing" which you can purchase anywhere i.e. Walmart (the cheapest). We tried the 3 day and then 7 day. After which we then slowly introduced food back into our systems. I found after 1 month, that for me it was dairy (I eat a lot of eggs), chocolate and certain meats. Each one of us were different in what we ate and were allergic to. To this day, my body still reacts to the same foods. Try this homeopathic way first before trying any more medicines. Also try to eliminate as much of the stress in your life as possible. Good luck.
