Kanina, still coughing since my last trip, want to cough out the phlegm also dun have, go air con room or smokey places keep coughing and coughing until my chest damn pain....
Alamaking, few years back I used to have cough similar to what you described which lasted few months off and on. Went to see few doctors, x-ray,etc .. without any cure.
Finally, I happened to meet this old Canadian French priest who noticed my cough and he gave me this recipe:
1) mix Brandy and hot water (ratio1:1)
2) add a table spoon of honey
3) drink all up
4) Go to bed (keep yourself warm)
I tried this and next morning the cough just disappear. Since then I swear by this cough recipe. Try it, may just work for you too.
