Californiagirl, I figured it was probably a misunderstanding along those lines, hence my attempt to clarify. Sorry if I came across as ‘pissy’.
Sadly the great night’s sleep did not translate into a day without EDS. I started getting sleepy about 1 o’clock and crashed completely by 1.30. I had suspected for some time that my EDS is not linked to lack of sleep at night. Obviously a lack of sleep at night is highly likely to cause fatigue in the daytime, but as I have had really good days as well as bad days, with only 6 hours of sleep, the link is not set in stone. Today’s experience really drove home the fact that night-time and daytime sleepiness have different mechanisms.
Night-time sleep is primarily melatonin based, but daytime sleepiness is primarily to do with adenosine.
I seem to have sussed how to get my melatonin working properly, but am nowhere near getting my EDS sorted. It’s really ironic because I have always had trouble getting to sleep and staying asleep (at night), but the EDS only really started about 20 years ago, so I’d’ve expected to sort the EDS more easily than the insomnia.
It’s very interesting that vitamin D is implicated in EDS, and curious that when I was living a lot further south than I am now, I had no daytime fatigue worth mentioning, but I don’t really think I can be deficient in vitD, as I still have tanned arms, despite the shorter days.
Sleep problems are not always rooted in deficiencies though, just as they are not always rooted in poor sleep hygiene. There are also variations in enzymes and brain chemistry that can have serious repercussions for sleep.
My problems with night time sleep are mostly due to an overactive enzyme, but slight deficiencies of other trace nutrients also have noticeable effects.
I haven’t quite finished but it’s bedtime, so I’ll wish you all as good a night as I had last night!
Good night all! 🙂
