I feel a little funk in my ears, along with a "different" type of headache.
I do not recall if this was the case last time? Being more aware of dangers w/ear eustation(sp) tubes it may be over blown but, defiantly going way down on peroxide content.

I have read 15ml to 50ml water~I would say DO NOT use 100% or even 50/50....go lower and add a pinch of soda. Not sure but perhaps has to do with high ph? i see the baking soda in every mixture on the net.

I do believe my sinus prob is gone, big yellow gloopy blasted out.

I know with water in ears swimming i would try pressure by holding nose/exhale DO NOT do this! maybe try the opposite, which i did to pull liquid out of ears.

Peroxide is very caustic, don't be careless!
