This is very interesting subject here!

For I too have the sleep apnea but also suffer insomnia. I like sleeping on my stomach and hope the mask they give me isn’t one that looks like an airplane mask. My father had one of those and I tried it out and could not tolerate that mask. I have CIDP too but undiagnosed as to what the cause is. But suffer dearly with sleep problems. And since you mentioned CIDP caused by Sleep Apnea. hmm! I have never heard of this before but would like to look into it further. That is something for me to check out since I have both problems and my body is going nuts. Very interesting hearing this.
