G.N.
here's what nobody ever suggests - stop using dairy products. as a long time smoker and someone who's developed a few allergies - i have to be careful about colds and anything that starts the mucus going. it's hardly ever about the lungs until it's gotten bad. it's about the sinuses. when i stopped doing dairy (milk, butter, ice cream, CHEESE!) i got better immediately. as a kid i got colds so often that wouldn't go away. and i loved dairy. i tried the Vicks thing on myself and it helped some but attend to the sinuses and it really goes away. also, there are several homeopathic remedies for allergies that work much better than conventional OTC drugs - and have no side effects. so i strongly suggest them. give it a try without the dairy for a week and you'll see a huge difference. my grandson had bad sinus issues and we kept him away from dairy. his sleeping improved 100% after being a heavy snorer and having dark circles under his eyes. good luck with it all.
