Try Chlorox brand the lemon flavor one.

buy cough syrup containing dextromethorphan, buy 2 bottles amd drink all at once.

cough wet or dry?

I used to have prolonged cough, once batuk kadang 5-6 months that is because not treated.

dry cough is when you cough no feel kahak in throat area.

bena expectorant is not that good (no cure)at least to me, there's pill type, or syrup, i prefer pill over syrup and I take non sleepy..

Go to any pharmacy and describe your condition to the pharmacist better.. last time I took sedilix (sleepy) and tussidex forte (non sleepy). the pills name I forgot already

Try Paraquat
