I've had copd for about 20 years. I take a pill for breathing and I use 2 inhalers and I have oxygen all time. I use the oxygen mostly at night and some other times. I'm 71 years old and I've been smoking for 52 years. I have tried to quit several times but couldn't. I quit 2 months ago and just smoked another one earlier today. I am trying so hard but it is so hard. I'm using the patches and they seem to help. I just had a rough week with family problems and let the stress get to me. I'm hoping to start a new day today.
