The last couple of days I’ve had a lot more coughing (and bringing up phlegm). Not fun.
It seemed all of a sudden, but I doubt it’s entirely random. My guess is that lack of sleep several nights in a row might have been a factor.
Regardless of the cause, I’m hyper-aware of how sensitive my lungs are feeling right now. Hopefully, another good night’s sleep will help them get back to normal.
