I have COPD Emphysema. I take Spiriva, Symbicort, Mucinex & I nebulize with albuterol inhalation solution on a daily basis just to get out of bed & move around. As the disease progresses I get tired. Not just tired but down right sleepy. I could, if I were a mind to, lay down & sleep for LORD knows how long. I don't because if I do I have to re-medicate as if it were morning. The results are weird, I go to bed before 10pm most night & My mind wakes up around 4:30am. If I just lay there quietly, I'll fall back asleep. But My mind wakes up again around 5:30 & I just get up. If I didn't fight the nap, if I gave in & slept, woke up, medicated & started over again (twice in the same day) I may not sleep well that night. I don't know cause i ain't given in. I'll Fight The Nap Till The Fight Is Out Of Me Forever.
