EJY, I have had problems with mask leaks. I do wake up at least a couple times a night, I just hit the ramp button if I need it. Sometimes even hitting the ramp button doesn't work so I will sit up, put my feet on the floor readjust things and lay back down. Sometimes I use the washroom and let the cold tile floor cool my feet good then jump back in bed and I am off to sleep again.
Are you getting sore in the ribs at all? I am and figure it is from the pressure. The soreness is slowly getting better over time.
Keep at it
Gerry
