For my post nasal drip, I do sinus rinses, but, instead
of the solution
going in one nostril and coming out the other, I start
it that way, then I open up the passage between my nose and back of my
throat, close off the other nostril, and force it to come down and out
of my mouth, to help clear the stuff out. I do this on both sides of
my nose. I do regular sinus rinses, also. Also when I go to lay down,
I have to have my head at, at least, a 45 degree angle.
