Does anyone have experience sleeping with a CPAP machine?

I am very likely going to be prescribed one of these machines in the next two weeks. After looking at the pictures, I’m a bit intimidated. I don’t know if I could fall asleep with all of that gear on my face. Has anyone here used a CPAP machine? Did it take long to get used to? Any tips or tricks for getting used to it?

I don’t think I get a choice in which one I get because of the way insurance companies seem to work, but if I do get some sort of choice, I’d also like to know which type worked better or worse for you.
