I had a sleep study done a 3 years ago and they could not get a good reading because client in bed in next room kept waking me up with all his complaints. So I am back at it again picking up a unit this Monday and wearing it at home for two nights. I do know I definitely have sleep apnea. So my questions for you all that have CPAP units what has been your experiences with the different types of units [full nose-partial] also what about sanitizing them. Should I invest in the unit that you see on TV all the time. I work with a guy that just puts his tubing in the dishwasher-not so sure about that. I would love to hear back from anyone that is currently using a CPAP. Thanks in advance.!
