Hi MoK,
I would suggest first trying to ascertain what thing or things might be CAUSING your problem - then you can better address the issue.
There are a number of health conditions that can trigger excess mucus production, such as:
acid reflux
allergies
asthma
infections, such as the common cold
lung diseases, such as chronic bronchitis, pneumonia, cystic fibrosis, and COPD (chronic obstructive pulmonary disease)
Excess mucus production can also result from certain lifestyle and environmental factors, such as:
a dry indoor environment
low consumption of water and other fluids
high consumption of fluids that can lead to fluid loss, such as coffee, tea, and alcohol
certain medications, such as certain birth control medications, and ACE Inhibitors, for example, lisinopril
smoking
