Thanks for your follow-up post, SusanEllen. One of the frustrations of this wonderful Mayo Connect forum(s) is that many folks don't post follow-ups so we are left wondering how they're doing.

I haven't heard of idiopathic hypersomnia, but I'm happy to read in your post that a treatment medication may help. All the best on that. Let us know after your appointment on the 30th how that goes for you.

Regarding my progress, I got fitted with a CPAP mask yesterday, and was instructed how to set up my machine and wear the mask. Last night went well for a first night. I woke up more than usual because of the newness of wearing a mask, but otherwise got a decent night's sleep, with incidents of apnea less than 5 per hour, which is where they want it.
