next June I will be on my 4th machine, I just can not sleep without it, and if you have some procedures at the hospital where they put you asleep, they keep me overnight since i use a cpap,Use it no matter how hard it is,there around 2000.00 dollars and insurance pays some,but ihave to fight with them every 6 months to get new hose and mask, there around 400 dollars for a hose and mask, thats why insurance is so high,I got lots of spare mask, hoses and last machine still works, but the one i am on now is starting tobeep during the night so got to call and get it checked out,Mine has a card in it and it reads the time you sleep and believe me the doctors read it they know if your following there instructions and using it,keep at it it will help,
