you now I am a frequent lurker here. I just saw what you said about your W's lack of oxygen condition. My dad has something similar and we figured it out beacuse he was ... sleeping all today and looked tired all the time. He was tested and it was lack of pxygen. They told him to use a mask during night sleep that "pushes" oxygen in. The first night he used it, he woke a different man. Energy, less sleep (by -50%), and better mood...
