My husband has severe sleep apena, he wears the mask & all. Two things that might help you that we had to learn on our own: prop up the head of your bed by at least 5 - 8", that will help with the snoring; and try sealing your mask with a touch of petrolum jelly along the outter ridge, that should not make the mask move without strapping it on so tight.

Both my FIL & BIL stopped wearing the mask because they thought it was uncomfortable, please do NOT stop wearing it without your doctors knowledge, it is very dangerous, it is like stopping your high blood pressure pills because you feel good.....not good!!

Good luck finding a mask. Tim was very fortunate that it fit him and he is please with it. Oh, and I am pleased too....now i can sleep with out being woken up!!
