Could it be alcohol induced? It doesnt matter if I drink Vodka or wine....same result. If I take Zyrtec befor bed I dont have the cough. [/INST] Hi Dear, Welcome to Chat Doctor. Understanding your concern. As per your query you have chronic cough which could be alcohol induced leading to chronic lung infection. Need not worry much. I would suggest you to visit pulmonologist once and get it examined. You should go for pulmonary function tests as well to check exact level of infection. You need inhaled bronchodilators and antihistamine Chat Doctor.  Furthermore, you should get X-ray chest done as well to find out exact level of infection. Furthermore, you should avoid intake of cold carbonated liquids. Avoid diet rich in fried and oily food. Take soft and bland diet. Take diet rich in multivitamins and vitamin C. You should take cough expectorants as well. You should use mist humidifiers in room. Hope your concern has been resolved. Get Well Soon. Best Wishes, </s>
