I have a CPAP since March of this year and I am still trying to get use to it. I could not use it during the sleep study as I got a panic attack and thought I could not breathe. I got past that and the I couldn't sleep with it on. Now I get a very dry mouth even with a heated humidifer. I had three nose surgeries and a throat surgery to see if I could go without the CPAP but they did not help. They say if you loose weight and exercise that you should be tested again in a few years. I am not sure if all doctor's say that. Just keep working at it and don't let it control you. Be determined that you can use it and keep trying if only for a few hours at a time.
