Young and dumb, started smoking in the 70s +marijuana. Almost 58 years old, not smoking cigarettes but marijuana for my pain. Not a constant use, but I feel it helps bring up (the nasties) green sputum and h er lips me breath without hacking up a lung. Sleep with a humidifier and try to stay hydrated as possible even though i pee every 2 hours. I sleep in a recliner or slanted with pillows if traveling. COPD BLOWS. Need to buy stock in tissues (gag rags). Looking for other suffers to be friends.
