Don, you can bank on the fact that lots of people read your posts with great interest, even if we don't intend to try what you are doing. Like Bill, I'm surprised at the apparently large volume Measuring your mask will tell us how much solution you used, a minimum estimate of total volume (assuming some solution wasn't spilled or swallowed). Any thoughts on how much volume is left or what the total volume of he sinuses and middle ear might be ?

Thanks
