A large percentage of the time I can have 0 leaks, often 0 AI, and for me I don't think ever in 2 years a 0 for HI. Except maybe during a short nap when I was so short on sleep that I just had to mask up and lay down in the middle of the day!
I find *when* the events occur has one of the biggest impacts on how I feel when I awake. If I feel crappy/dull headed and the AI number is 0 or very low, I likely had an few events in a row within an hour before I woke for the day...
I had immediate improvement during my split study....even with the headache the mask gave me from sitting on my face/sinuses. I was thrilled to trade THAT headache for the oxygen deprived and fractured sleep headache I had had daily for so, so long!
CPAP has helped me be able to focus in on OTHER issues affecting my sleep and functioning..... gives me more sleep and so some more energy to face and think thru the other elements.
If I had expected miracles and a cure all immediately from CPAP, I might be disappointed. Rather, I see and celebrate every little thing that improves during this CPAP partnership.....even my toes!! (do a search!!)
