I have been on the machine for 5 years. I own three of them, one for the bedroom, one in the living room for a quick nap, and one in the camper! They are a life/marriage saver! My DH and I moved into separate bedrooms about 15 years ago due to my snoring, so I had no one to inform me that my apnea was bad. During my sleep study 5 years ago they woke me after an hour and a half and put the machine on me. I slept peacefully for the first time in years!! I highly recommend it and want you to give it all you have to keep it on...The first night I hated it...the second night I fell asleep and slept soundly....that's all it took! I go no where without it!
