He has like 600 mg. potassium, and B1. Maybe I should increase the potassium. I don't think he is on any natural diuretics. For anybody else reading, do not do antihistimines. I think he was detoxing which made the mucous worse. Got some Xylitol for his neti pot, that really helped, went back to Mucinex, some euclyptus pills, clears the sinuses. The holistic pharmacist mentioned Quercetin for inflammation. I see it mentioned on Dr. Amy's site. Anybody try this? I took one yesterday and got a headache, but there was also a weather front coming through.
