The first time cough for more than 2 weeks in my life. It started from a minor cold, relieved after visiting ENT specialist but rebounded with allergic cough which could wake me up in the middle of the night. ENT specialist medication could not completely stop the cough.
Changed to visit respiratory specialist Dr Chan near my office with more focused medication on allergy and cough syrup with codeine (tasty ^_^) inevitably feel a bit dizzy but cough abated. Second visit, Dr Chan has reduced the dosage accordingly, recovered completely before finishing the full dosage. Price is reasonable for specialist treatment around $700 - $800 with 1 week medication. Recommended!
