I AN CURRENTLY FIGHTING EXCESS MUCUS WITH COUGH AND CANNOT GET RID OF WHEEZING. I CAN COUGH UP MUCUS BUT STILL RETAIN WHEEZING. LESS DIFFICULT SITTING / STANDING BUT VERY DIFFICULT LYING DOWN. PREVENTS SLEEPING!
ANY ITEMS OR SUGGESTIONS REGARDING HOME INTERVENTION SUCH AS HONEY, LEMON TEA MIXTURE OR SIMPLE REMEDY FOR CONTROLL WITHOUT MEDICATION?
THANKS WITH REGARDS
