Excessive fatigue is a symptom of many conditions other than COPD. I'd suggest you get checked out to begin to eliminate some possibilities.

Look up hypercapnia and ask questions about it! It happened to me.

Thank you, maybe just being more active thru the holidays. Hope your holidays were good.

I sleep a lot also but not that much! Maybe there are other things wrong with you, I have other health issues that have caused me to be sleeping more than usual! 🙏🙏🙏🙏🙏 Praying for you
