@mhjohnson — oof, rough night! Hope tonight’s better for you.
An expectorant does help move the mucus out. :)
I’ve had situations where I take a cough suppressant at night, to get restful sleep, and then take an expectorant when awake to help move the infection out.
Whenever possible though, I avoid taking a suppressant and just take an expectorant! (Fenugreek works great for us.)
