I had sleep problems that started with some neurological problems prior to my developing CFS. I, like many with CFS, have unrefreshing sleep plagued by frequent wakings and bouts of insomnia. Quite frequently I will startle awake several times a night as if my body let loose with a bunch of adrenalin. I have been diagnosed with sleep apnea and shallow nighttime breathing. I was not obviously deficient in nighttime oxygen since I do not snore and have no extreme daytime sleepiness, apart from the fatigue. It was only during a sleep study that it was discovered that my oxygen levels were dipping quite low (in the mid 80's and occasionally a little lower) for short periods. I am know trying to get use to a CPAP machine, which is not conducive to having insomnia Anyway, one thing that I find paradoxical is that I the more sleep I get the worse I feel that next day (greater CFS symptoms, higher pain levels, etc...). On nights that I have broken sleep, as if I have too much adrenalin, I have less fatigue symptoms and less pain the next day (although I have to be careful not to do too much). I have been trying to put some type of connection together. Maybe since I was getting lower amounts of oxygen for a longer time on nights that I received more sleep, thus the overall worsen of symptoms the next day. Or it seems that the more actual time lying in bed directly relates to inactivity symptoms such as pain, fatigue, etc... Hmmmmm I was just curious if anyone else had similar experiences.
