I passed this on to my wife.
I use a C-Pap machine to sleep
OK—do you also have oxygen? I have a cpap. It really helped me too. However, I noticed symptoms returning, and asked my doctor to do a follow up test.
CPap alone was no longer therapeutic. So we had to add the oxygen to keep oxygen at acceptable levels.
Have you ever tried that So Clean Machine they advertise on tv? It really does a good job mask and every thing just reeks of clean. I got the portable one so I could clean it if the electricity goes off.
