Hi I was first diagnosed with severe sleep apnea back in 09 and again this year. I used a ResMed Escape II for about 2 years and then had a sinus infection so I stopped and then I lost weight so I felt I was sleeping well enough. During the next 5 yrs, I went thru menopause, gained my weight back, and had to change my insurance. So this year I wanted to start using my old CPAP but had a hard time finding a supplier here that used my insurance, and I doubted my first study. My Dr. agreed we should do another sleep study since it was more accurate today. I had my sleep study a few months ago and just this last week got a new Dream Station Auto CPAP with Respironics. I am not doing as well this time. I feel the c-flex is too low and find myself wanting to gasp for air, so that needs to be adjusted at my check up next week. But I also feel dead tired when I wake. I sleep thru my snooze button and find it hard to wake up at 6AM. I do wake fine around 3AM and then find it hard to want to continue wearing the mask. I have to use it 4 hours min. for the insurance to pay for it. I hope the morning tiredness is temporary. So that's my story. Thanks. I am glad to find this site.
