Thanks Amazoniac.
Ps: I forgot about it but after trying a water soluble decaffeinated coffee I had immediate issues twice, so particular instant coffee brands may use bad chemical processes.
Honestly I've tried to identify triggers but it's hard, I will say that I have almost none now, and the last time I got one was clearly tied to bad gut health (fish and dairy thread). Perhaps things differ depending on people, as for me I suspect hard cheeses are bad. Dairy in general may well be a culprit, same for certain types of fibers ( some fruits, veggies). Travis has talked about the connection between opioids (cow dairy?) and mucus secretion. Of course during hay fever things may get a lot worse. Haidut mentioned mb clears nasal congestion, I've heard about xylitol rinses, but an othet thing which I'm using atm and which may be helping (also allergies?) is bromelain. It is a blood thinner so not sure if a dependency could develop. The examine. Com guy mentioned bromelain and ephedrine (double check) keeps his nose anf sinus clear. Chewing a very small amount of fresh horseradish may help. If it is gut related then maybe a combination of charcoal and cascara can help?Did you ever track down the sinusitis?
