First night pressure question

Thanks for the replys. I likely did sleep on my back starting out. I was so worried about the mask not sealing, that I was nervous about sleeping on my side. Reducing my max pressure makes a lot of sense to me-especially till I get a little more used to things. I was really surprised that the first night went as well as it did.
Thanks again for taking the time to help out a "new guy". You really cannot imagine how even a little bit of encouragement and help goes

Thanks
Greg
