Well, both you guys sound just like I've been in the past !
At the moment I'm sleeping virtually all the time. I have difficulty summoning enough energy to stand upright - even when I do get on my feet I tend to have peroiodic "droops" where all my back muscles seem to just lose energy and my shoulders sag. (I usually look for something to lean on.) Things are looking up though - yesterday I managed to stay on my feet for about three hours, and the same again today.
Oh for the days when I used to bemoan the fact that "I only managed to dig thirty yards of ditch today" or fell forty trees, or build not-quite-two cross drains.
But as I was snoozing to the sound of my downstairs neighbours thumping bass music this afternoon, I was sleepily reflecting how much nicer it was to be able to sleep too much and at least wake up with a little bit of energy for a little while, than the "good old days" when I was too tired to even sit in a chair but had horrendous problems trying to sleep...and would even wake up more tired than when I went to sleep ! Eternity itself spent sleeping does not seem to have enough hours to overcome such fatigue. I'd guess this is your situation, Tennessee. In which case you may be glad to know that I know a fair number of people who have been through this, and come out the other side. It can go away.
When I first started suffering from chronic fatigue, I was extremely active with cycling, ski-ing, backpacking, running etc. The first symptoms I noted were a tendency for my body to over or under heat during exercise - I sweated and chilled more drastically. The other tell-tale sign was that I started to take much longer to recover my energy after any activity. But in between these bouts of severe fatigue where I had no energy at all, I had whiles of almost normal energy levels. During which I tried to get as much done as possible, to make up for lost time...boy, that was a mistake.
Eventually as time went on and I kept on trying to ignore my fatigue, it encroached more and more on my life, I became very depressed, and eventually the fatigue was more or less constant and severe, as opposed to episodic.
Nowadays, in retrospect, I would say that my food intolerances had a huge amount to do with the severe "can't move, can't sleep" fatigue. In fact I call this sort of scenario "instant starvation" and usually try to overcome it by resting in bed if neccessary - not trying to sleep, just lying listening to music is as good - then eating a cooked, protein based meal afterwards.
Generally, I find that I will then have a relatively high level of energy for a few hours, until the nutrition wears off.
So why don't I have any energy just now, if I have it sussed, I hear you ask ? ( Good question. )
Because I have Crohn's Disease - which is probably the root cause of my Chronic Fatigue - and when my gut is particularly badly inflamed, it does not absorb nutrients well. Eating makes me ill, and I have to balance the trade-off between improving fatigue and worsening other symptoms.
But that's just me. Lupus, Fibro, MS, and a whole host of other auto-immune disorders can cause severe fatigue, not to mention viruses, infections of almost any sort, thyroid problems etc.
So as Brynn pointed out Charlie, it would be a good idea to see a doctor. IMHO, preferably a rheumatologist (specialist in inflammatory diseases) as they tend to be much better at diagnosing fatigue related disorders. The road to diagnosis I'm afraid is generally long and full of educated idiots. Most doctors are not inclined to consider fatigue a "serious" problem - right, Tennessee ?
Hope this helps....
