My SO has been on a CPAP machine for about a month now and it really seems to be helping. Two problems he (we) are having with it. First, his machine is the kind with a warm air humidifier. The tubing from the machine to his mask tends to get water in it during the night which wakes us both up because it gurgles. We are not overfilling the water reservoir. Second, the forehead pads on it are uncomfortable to him. I'm thinking of trying to make little soft pads out of material to cover the rubber? We're going to ask his nurse about these things, but wonder if anyone has found their own solution. For those of you that don't know, CPAP stands for Continuous Positive Airway Pressure. It's a machine to treat Obstructive Sleep Apnea.
