A similar fix for me was a nasal steroid taken every night. Got me off the CPAP
Last week I asked my PCP about a middle-ear blockage, and he said the F.P. should do the trick, and perhaps also relieve the dry, itchy eyes I've been suffering.
I suspect that I have been dealing with OSA for several years now, so... the nighttime dosing seems like a good idea. We'll see how it goes!
