My question is this: aside from "lowering the pressure means that you don't have to deal with the issues of higher pressure", are there any down-sides of having a CPAP pressure that is too high?
To put it another way, imagine that you are completely comfortable with the pressure you are currently using. You then have another sleep study and find out that a lower pressure will now be an effective treatment. What is the down-side of staying at your current (higher) pressure?
By the way, I am not in this situation. The question is pure curiosity.
