I've seen a couple people on this board mention Delayed Sleep Phase Syndrome (link here: http://en.wikipedia.org/wiki/Delayed_sleep_phase_syndrome), and boy is that me. And near as I can remember, bad sleep started when my autonomic stuff started. I try EVERYTHING to get good sleep at night but it just doesn't help, or it helps only marginally. My "good" sleep starts at about 6 am - which is a bummer, because I get up for work at 7:00 or 7:30 am . Naps are also very deep sleep for me, unlike overnight sleep. Again, I have no idea why other than possibly DSPS, which I've known about for all of 24 hours. When I did a sleep study it showed I roused 30+ times and came fully awake 14 times by 2 AM (the doc just stopped counting at that point). No apnea, but almost no Stage 4 deep sleep. Sleep issues seem like a common problem for us ANS-ers, yes? The only good sleep I've ever had since all this started is either medicated to the eyeballs on something like Versed, Valium or Ativan (I used to look forward to hospital diagnostic tests because I'd sleep so well afterward!!) or once after a Kirtan chant. (And I've tried duplicating the chanting experience at home, doesn't work). Of course all of the meds are a no-no right now with the pregnancy, so it's basically occasional benadryl and mostly just suffering and napping when my schedule allows it. My cardiologist never liked the benzos though, but after baby and breastfeeding I might bring it back up again, since several people seem to have success setting their sleep schedule at night with some low-dose benzos. There is something called "binaural beats" (it's an audio thing) that's supposed to help put you into deep sleep. There's a company called Acoustic Sheep that sells headphones you can wear to bed, and they also offer downloads of white noise or waves with binaural beats woven into the sounds. I think that's actually what happened "live" to me with the Kirtan chant. It's not a cure-all for me because I have to sleep with earplugs b/c of my husband's snoring, so the headphones can't be an all-night thing. But maybe it would be worth a try for you! Good luck with getting good sleep!!
