Perhaps you should ask your doc to do another CPAP titration study to check that the pressure he/she has your machine set for is correct. After I had problems, despite a CPAP machine, my sleep doc said that my titration study had been ambiguous and he had initially chosen a comfortable low setting of 8 inches of water. So he reset it for 18 inches and I was fine, although the higher setting took some getting used to. More recently, I needed to replace some equipment and my supplier advised another test to see if my level had stayed the same (if I needed more than 18 he said he would have had to get me a BiPAP machine instead of CPAP). That test showed 8 inches again. I've been using that, but occasionally while I am still awake feel like its not giving me enough air, and I sometimes take the mask off to get a deeper breath.

:yawn: Here is my story. I am a 45 year old white female whose BMI is within the obese range. For the past year, I have been using C-PAP after being diagnosed with sleep apnea (30 events an hour). During the past year, I have lost some weight. However, I know I need to lose more. For the past several months I have had terrible daytime sleepiness-falling asleep at work, at home and in traffic. I am being treated for depression. My pdoc gave me samples of Provigil to try. I can not take the med because it causes me to have high blood pressure. I have low tolerance for excercise. Now here is the main issue-I have so much trouble getting up in the morning. I am always late for work. Having tried multiple alarm clocks, alarm clocks across the room, different types of alarms-buzzer, bell, beeper, music-I bought a Sonic Boom alarm clock with bed shaker. Even this barely wakes me up. I go back to sleep! I do not know what else to do. I am so frustrated. HELP!!:yawn:
