My husband and I both have sleep apnea and have been on CPAP for a few years. He uses the nasal pillows and I use a full face mask. It made such a difference in our lives. Before, I wasn't getting ANY sleep due to his loud loud snoring and gasping. A few months after he got his CPAP and started sleeping better, I discovered that I was now the one snoring and gasping. The CPAP has improved the way I feel, and I'm not falling asleep at my desk at work any more. We both use the CPAP every single night, and I even use mine on the rare days that I get to take a nap.
