HI,
Most people love the CPAP after they get thru the adjustment period. My problem was made worse when I put the mask on to tight, it can and will bruise your face if its to tight.
I found that after some practice you need to learn how to pull the mask away from your face after attachment the air pressure to flair the seal this allow the mask to work better.
My cpap test was so bad the tech came in and put a mask on me, he said I was scaring him when I stopped breathing 29 times and hour.
No wonder I was so tired all the time and that question about falling asleep at a red light was very true for me..

I was drinking two pots of coffee a day to function.and my wife sleeps better now she loves that I don't snore anymore..
psps My work was shocked how much my personality improved being tired does make you snappy and grumpy.
