back2good - it might seem like people are nosey and pushy asking about the details about your mask, but they're all extremely helpful people and want to assist you.
Your mask is really THE most important item in your XPAP gear as it's what you wear strapped to your face each night and a bunch of experienced posters here would have used the same mask as you, so can offer lots of advice and suggestions.
The more info you can give the better we can help you. Btw, you can add your mask as well as your machine to your signature, and actually - the text version is much more helpful than the pics as many machines/masks appear the same but they're not.
Hang in there - it may just take a little time and tweaking to sleep comfortably with XPAP.
