Ruth, my mask only goes over my nose. I have two straps that go around my head just above my eye level, and two straps that go around my head just under my ears. If you lay on your side, the straps between your head and the pillow seem to "drag" on the pillow, so you can move your head just a little to adjust the intake from the machine. Move your head around just a little until you feel the most air going to your nose. You'll be used to it in a day or two.
Kathy, congratulations to your grandson and his fiancé!!
(My parents also got married on July 4th; a wonderful day to declare their interdependence, and enjoy fireworks afterwards! :)
