I just stated CPAP with a full face mask. When purchasing equipment My specialist asked if I sleep with my mouth open or closed. i said I haven’t the foggiest idea b/c I am sleeping! So she suggested starting g with a full mask. My question to the group is: Even if I do sleep with my mouth closed, is there any downside to using the full mask other than the size and discomfort? Also , does anyone switch off between full and nose only?
