I doubt the water in your ears contributes. If you see my notes above, you will see the mucinex helps. But one thing people forget to do in winter is to stay well hydrated because we are not sweating, so we don't feel thirsty. Do whatever works to remind yourself to drink more water, herbal tea, flavored but unsweetened waters. My Mom used to drink water with a squeeze of citrus juice in it.

Also, if you don't have lung problems, you can use the old-time trick - inhale over a basin of steamy hot water (with a towel over your head to keep the steam in. DOUBLE bonus - when you finish, massage lotion into your moist skin - it will soothe winter dryness.
