I've been through this recently! I had trouble focusing during the day and didn't realize it was due to poor sleep quality. When I started researching CPAP machines in Canada, I looked for ones that were easy to use and had features like ramp time and automatic adjustments Insight. I ended up finding one with a solid return policy, which gave me peace of mind while I got used to it. Honestly, it took a few weeks to get comfortable, but now I feel like a different person. Much more rested and alert — totally worth it.
