Exhaling is awful, it makes me hyper-aware of my breathing, which makes it harder to sleep, and if I have a runny nose or if I have to yawn, well, I need to yank that thing off. Have we really not come up with a better treatment for something so common?
There are CPAP models that reduce pressure on exhale so it's not so difficult. Essentially mimicking a BIPAP at lower pressures. What machine do you have?
