I used to shake my head really hard. Then I heard a really loud pop once and I got a little light headed... that was the last time I did that. Other than that, I've never had water that wouldn't drain if I made myself sleep on whatever side. Gone by morning.
i THINK that i've heard of the alcohol or peroxide thing too... i think its because it displaces the water so it will drain and the alcohol or peroxide evaporates faster.... but don't do it cause i said so, i'm just saying i think i've heard of it too...
water & vinegar to help dry, and when i got an ear infection a few weeks ago my doctor told me to hold a blow dryer up to my ears for a few minutes on low. at the sign of any infection, go to the doctor. dulled hearing, pain, itching, ect. I waited two weeks after I got symptoms due to basketball camps, and ended up getting a middle ear infection. They hurt so bad I could barely sleep.
Back in the day, I used to use a product called "Swimmer'* Ear". It came in a small squeeze bottle. All you had to do was put a couple drops in your ear and it would work it'* way to the pooled water and help evaporate it. Google it. It might still be available.
But that was then.... I've since learned a new trick that works great (but don't laugh). You know that little piece of meat/cartlidge on just in front of your ear hole? At the base of the cartlidge, push it in toward your ear hole. Release quickly. Do this repeatedly. The suction created by pushing the cartlidge into the ear will eventually work the water out. Do this in combination with bobbing your head left or right to work the water out.
