I have had such issues with sleeping that I created an online forum/community for people with such issues haha. Fitting, I named it cantsleep.com ;)

I used to drink so much nyquil it lost its effectiveness.

Jimbo, i know a few people with sleep apnea and they say exactly the same thing as you, getting used to the mask is actually the hardest part. After that, you are happy and can finally enjoy sleep again.
