Hi DLB2, and thanks for your post. While others in the community may respond with their own personal experiences about COPD and feeling tired, I thought you might gain some additional insight from any of these articles on that very topic. They are published right here on our COPD.net website. For your convenience, here is a link to several of them: https://copd.net/?s=sleep.
I do hope you find them to be helpful.
Wishing you well,
Leon (site moderator COPD.net)
