Last night was night 7 of my CPAP.
A friend told me the experience of his brother, who "became a different person" with his CPAP. Most notably, he said that while the CPAP solved the immediate problem (sleep apnea) fairly quickly, it took him several weeks to get caught up on his sleep deficit.
I think both observations apply to me.
Last night we turned off the light at about the same time, but instead of waking up when Sally's alarm went off (she unlocks the front door at 6:30 so the grandkidlets can come in, mom starts work at 7:00), I was totally zonked until after 8:30.
And I feel better, more refreshed, than any of the other CPAP nights.
This is exciting!
