After every time I eat anything I begin coughing until I get the phlegm out of my throat. It is always clear, but it is quite thick. This has been going on for 4 to 5 years, but it didn't used to be so bad. It used to happen only after I ate spicy food or food that was really hot. Now it happens after everything that I eat. I do not seem to have any other symptoms. I do smoke about 1 pack every 2 weeks, so not that often, but i do. I thought that maybe it was allergies, but I don't really have allergy problems. I hope that i have not left anything out. Please help me to find out what this is and what I can do to fix it if possible.
