Follow-Up: Not sure if I can offer technical support, but I did see my best friend try what I assume to have been a proto-type CPAP. It was a device that had a pump unit, which fed a breathing mask, worn by the person. The mask was a positive demand system, causing a slight +pressure to be breathed in. If I sound like I don't know what I'm talking about, it is because I don't;however, I did see the difference in my fried. He loved it and could not wait for bed. He said it took him a few weeks to adjust to sleeping with the mask/bag. I think it is all attitude. If you want it to be bad, it will be. You want good results, you'll get it. I can't relate to the sleep apnea, but each of us has had to go through our own special trial of life. If your upbeat, thats who you are and nothing can get you down. Again, I'm not an authority, but have been breathing in and out for 50 years, so I have experienced some hard spots of my own. Humor works for me, but do what works for you. Jerry
