Logic late at night

I am pleased with myself for having successfully used logic at horrendous-o-clock last night.  [Warning: trigger for icky cold details.]

Background:  My husband and I both have an annoying multi-part cold that's been going around.  He's ahead of me by a day or so.  In his case it's just been various forms of miserable, currently in the long-recovery phase of a fair amount of coughing at night.  In my case it started out with post-nasal-drip throat, felt better after a few days, followed by significant head stuffiness, followed by the onset last night of the Serious Post-Nasal-Drip That Gives You A Bad Cough So You Can't Sleep part.

Come horrendous-o-clock (all I can tell you is it was sometime past 3:15 AM), I've tried propping my head and shoulders up with pillows, which doesn't help with the drippy and the cough.  I've tried putting my pillows against the wall and sitting as upright as I can manage, which also doesn't help with the drippy and the cough.  At which point, despite my fatigue, it occurs to me to try lying relatively flat, because the crux of the problem seems to be stuff dripping into my throat.  So, what happens if the crud isn't allowed to come into my throat? Happily, I'm finally able to fall asleep!

Wonder what will happen tonight?
