Hello. Just joined the group. I was diagnosed with severe OSA in 2005 and have used a CPAP for 9 years. I have to use a full face mask and do not like it. At the beginning, I wanted to take it off and throw it across the room. I learned to tolerate the mask, and will not sleep with out it. Last year I had gastric bypass surgery and lost 130 lbs with more to go. They say I may be able to be free of my OSA, but I know it isn't yet. I dosed off without my CPAP and woke up struggling to breathe. My sleep doctor plans on another sleep study next fall to see any changes. I must say the rest of my health and quality of life has improved.
