Try some exercise such as running.  That will get the cilia moving.

A hot drink or food may also help.

Hi Lucy.... Lie on the bed with your head facing towards a shoulder.
..Pinch your nose (hard, just below the bone), now swallow. Hold the
nose for another 15 or 20 seconds.   Very lightly ...I repeat.... _Very
Lightly_    blow your nose.  Repeat facing the other direction.  This
works wonders for me, not only for removing the water, but mucus too.
