I have been smoking meth every day for the past few months. About 5-10 hits every morning and maybe a couple at night. I try to eat, and am constantly drinking water. I sleep every night, but I can t stop coughing up stuff. I always am gagging on thick phlegm building up in my throat that I can t cough up. What should I do to get rid of all this gross, discolored, bad-tasting mucus?
