Seeing a pulmonary Doctor the last few months. Got a breathing test done at hospital ( one where you sit in a machine). Dr said I have moderate copd, stage 2 i guess. Prescribed Trelegy, using it for a couple months Now. Once a day is good for us who forget that second dose. Seems to be working well. Good to share with others who understand copd. Merry Christmas to all and easy breathing to all.
