I am a smoker and may of the times I get cough and my nose gets blocked starting from oozing out water then turning to yellow and liquid cough and even some blood patches. It usually happens that whn I smoke I get all these issues and when I quit this for few days and take some meds it disappears. What medicine would I prefer and what are the precautions to be taken. Currently I use Cepodem, azicip and montemac.
