Thanks for your help folks. Kat, Ididn't realize that the canula & nose pillows were one and the same. That is in fact what they tested on me. I mislead you when I used the word mask. Sorry. I had a 6 hr. nose bleed when I left the clinic-so it must be very drying. Funny thing, all the while my nose was pouring blood, I felt GREAT! I wanted to go out and chop wood.Very alien feeling. It sounds as though you have the drynes beat with the water bottle attachment. I'll find out about that. MichaelM sorry it didn"t work for you. Funny, I thought only 2 or 3 people would answer-must be a lot of this going around. Most appreciatve for your help.
