Last night was the first night with the CPAP. I was able to use a smaller mask rather than a full face one, and slept wonderfully. We'll see tonight if that was all placebo effect or if I can start to regain my sleep deficit.
Maybe not. I've known quite a few people that get very cheap tickets at the last minute. The airline's gonna eat the cost of the empty seats, anyway. It's all about finding the right flights at the right time, unfortunately.
