I have a new Respironics Comfortgel Full mask. It works pretty well so far, but this one and a previous Respironics, presses against my lower teeth and lip. I am very sore in this area. Anyway, I have tried a larger size this time around and I am using a Large. I have been told that you can mould the gel to fit your face. I am thinking maybe this will help the fit around my lower face and ease the pressure at this one point. Has anyone moulded their gel mask and how did you do it?
