Hi . I see you are new to the community. Welcome! Did you just start using a CPAP three days ago? Adjusting to the machine can be really hard at first, especially if the mask doesn't fit well. Is the machine itself keeping you aware or are there other stressors that are contributing? Here is an article about adjusting to a CPAP machine that might interest you. It took my husband a few weeks and a few mask changes to get used to his. It's been more than a decade now and he can't imagine sleeping with out it. I hope this helps and that you get some sleep tonight. Thinking of you. - Lori (Team Member)
