If I am in horrific pain or absolutely exhausted,I sometimes get under the covers and it is like I am not awake and not asleep. I also have the unable to move feelings but don't know if I really can't move. I had a diagnosis of narcolepsy a long time ago which can mean anthing from excessive daytime sleepiness to actual cataplexy. I am not sure if it was trumped by CFSFM and really don't think I have CFS. There is something called "sleep paralysis" which can happen with narcolepsy as well the general population but with Narcolepsy it is much more frequent, sometimes to the point of being unable to drive and completely disabled. I don't think this is what I am experiencing. My psychiatrist said it might be a physical response to the pain. Until reading a couple of posts today where people were describing this same feeling, I had forgotten about "sleep paralysis". If it is not sleep paralysis, which is neurological, I would guess, again I do not know for sure, that it could be neurological. Anyone else experience these feelings? This is kind of cut and paste to my response to a post. I am too tired to be original, LOL!!
