Hi, got too busy to post results: husband took out cotton after 20 minutes not overnight, said he didn't hear me (ha ha).
Good results on bot sides, tho. Big dark wax piece out on 1 side, the rest allwet sand-y like. He can hear better now! He has hearing loss, mild, from untreated earaches when a child. And, the omega3s we used are fishoil derived, so there's a slight odor, but that is gone soon.
I'm impressed, especially we were using some expensive homeopathics with slight results.
Please don't ask where I heard this, but excess ear wax is supposed to be caused by insufficient Omega 3s in diet. Bought some capsules today, popped 1 and poured 1/2 into husband's ear then cotton piece for overnight. Will see in the morning what comes of it (out of it).
