Well, I finally got my autopap machine set up yesterday and I used it for the first time. the mask feels very comfortable and the pressure feels good too. I have a resmed and I really like it. However, for some reason, as soon as I fall asleep, I wake up usually with heart racing at least a bit. I really don’t know why :(. The only thing I can think is maybe, my brain is still trying to wake me up and hasn’t ‘learned’ that it doesn’t need to yet since I have a machine now? I don’t know T_T Is this possible or am i just crazy? I want to have hope that I can adjust to this machine and properly fall asleep with it so badly.
