Re-read the following and realized I kept talking of myself and my concerns. Please excuse this rudeness. First thank you both for replying to my writing; makes one feel that isolation is not the name of the game and there's thoughtful commentary around us. Secondly, I hope your experience with this therapy is working better and better as time goes by. The difference before and after seems to have potential for serious increase in quality of life. Good sleep and breathing.
Sorry for the delay in response, but life is... and it's given me some time to try out a couple of ideas. Bottom line is that at some point beyond initial few hours of sleep, I'm waking up with lots of pressure and no way to relieve it short of turning the unit off and restarting with a 20 to 25 minute delay. This way, I can relax into some pressure and therapy and fall asleep for a longer period of time. However, waking up is still filled with too much pressure, being unable to rhythmically breathe and finding my belly bloated and aching from the effects---though to a lesser degree than earlier. Yesterday, was able to walk well for 2 miles without too much discomfort and a fairly sufficient breathing pattern. The bloating/cramping seems to push up into the diaphragm/lungs so it's not possible to breathe fully.
AHI seems to be quite variable. However, over the last 20 nights it hasn't risen above 9/hr, with an average of 7.78 and am sleeping more hours, more consistently. Waiting to talk with my dr, though am not sure he really knows specifics about this process. When I saw him last, he nodded and said getting used to the process took a couple months, etc, etc. Then the tech at the medical supply place (who was to work with me that morning) slid me off onto the next month I saw the dr. 00.00 assistance --- GRRRRRRRR.
One thing that stays with me is the possibility that the machine is actually malfunctioning. Earlier, at a different location on this site, another patient detailed similar difficulties and she found that her machine (another ResMed) was malfunctioning and received a replacement. As a result, I'm emboldened to push past this laissez-faire attitude and find out if my equipment is operating abnormally. When I do have a good and lengthy sleep, my day is so much improved. One morning I actually felt like my old self. I want to get entire the system working well to have that kind of waking-up and day more often.
Quick additional question: 1. Does your unit get warm to hot during the night, even with plenty of water? When I put the mask and tube back to work after a 2-3 o'clock break, the pressure is warm. In the morning the water container is noticeably warm, working on hot.
