Here is something I have been wondering. Should I try a nasal cushion, like the PR dreamwear nasal cushion? I was started on the FFM Simplus and from reading many reviews of all different types of masks, the Simplus seems to be more of a "leaker" than others. Plus, if I am using the cervical collar either way to deal with my mouth drop issue that causes mouth leaking on the FFM, then why can't I use a nasal cushion + the soft cervical collar? Would it seem better to try a nasal cushion first, or try a different FFM such as the Airtouch F20 to get mouth leaking under control?
Does anyone have specific experience switching between these different types of masks and the factors that should be considered? Supine sleeper who rolls to side sometimes, but has chin drop and uses soft cervical collar.
