Wow I'm sorry to hear that, but it's also refreshing to hear from someone with a similar experience.
> just a more extreme case of the first is a complete inability to wake up.
> everything feels so exceptionally tired and heavy that I feel like I don't have the strength to move anything, even to turn my head.
I've tried to describe this feeling to others, but it's difficult. I call it my "death sleep," not to be dramatic, but because it's like waking from the deepest, most complete unconsciousness I can imagine. The heaviness in my body and chest make it feel a burden even to keep breathing; so I fall back asleep quickly.
After months of this, and visits with many specialists including a cardiologist, endocrinologist, and pulmonologist, an MSLT [1] gave the diagnosis of Idiopathic Hypersomnia [2, 3], which makes me laugh when you break it down: ("idio" = Unknown, "pathic" = Cause, "hyper" = Very, "somnia" = Sleep).
That diagnosis, while frustratingly vague, has at least allowed me to be prescribed medication that has made a big difference in my day-to-day alertness.

That's the best guess my family doctor can come to as well. I've not been given a formal diagnosis, but we have proceeded assuming that is the case. Unfortunately that doesn't lead to many options for treatment. Modafinil helped to keep me awake but laying awake through those major episodes was a special kind of hell that I didn't want to live through. Methylphenidate has helped to keep me more alert and capable during the minor episodes, though it doesn't seem to have affected the major episodes. The only other treatment available seems to be Xyrem but it's really expensive and the side effects don't seem worth the risk - there's a very real chance of dying in your sleep. I find it funny that I would be trying to treat an ailment where I'm unable to move or wake up by taking a drug that will ensure I can't move or wake up.
The only other diagnosis that seems plausible is Klein-Levine syndrome. I'm hesitant to believe it's that because it doesn't explain everything and it's quite rare, but the major episodes sound similar and that's a rather unique symptom. I would say I also experience the increased hunger during those episodes. They do tend to last at least a day with periods in between where I will be awake but groggy for a few hours and I'm usually insatiably hungry during those breaks. However, if that's actually what it is, it's even less understood and treatable than idiopathic hypersomnia is, so other than having a name to put to it, it doesn't really help any.
That's why my doctor and I have just kind of left it where it is. We have tried the available treatments for these conditions with some limited success, and otherwise there isn't any benefit to having a formal diagnosis. In fact, the sleep pathologist suggested I may not want to pursue a formal diagnosis because, if diagnosed with something like narcolepsy, I may lose the ability to drive. My symptoms aren't such that I would become incapacitated without warning, but even just putting that name on it could lead to being treated as if that were the case.
What are you prescribed? Similar situation; still trying to find the right meds.
* Modafinil (400mg, 1x daily) - Started with 100mg and tried several variations of timing/dosage. Currently, 400mg upon waking in the morning has worked the best.
* Duloxetine (30mg, 2x daily)
My PCP prescribed the Duloxetine early in the process when they suspected I had ME/CFS. It did not seem to do much other than make me feel calm in situations that would normally cause anxiety, but later I got the IH diagnosis and was also prescribed Modafinil. My PCP offered to help me stop the Duloxetine, but I decided to stay on it because: 1) I was so grateful for the relative energy I had after starting the Modafinil that I didn't want to do anything to compromise that, and 2) I was enjoying the anxiety-reducing effect.
The Modafinil has not completely relieved symptoms; I still have fairly bad sleep inertia and will crash with a "sleep attack" about once a week, but that is far better than before, when I was sleeping 11-18 hours _every day_.
Sorry--I'm sure that's not too helpful to you, as it seems Modafinil is doctors' standard starting point for IH "treatment" (at least in the US).
Edit: Oh, and despite the "warnings" in the Modafinil instructions, I also drink about 3 cups of coffee a day (stopping at noon), and I feel that has been a vital supplement.
What has your experience been?
Not the person you responded to, but thought y'all may be interested: there is a promising new class of drugs for narcolepsy type 1, orexin agonists, that are yielding great results in clinical trials. TAK-861 is in stage 3 trials now I believe.
As I understand it, the best theory of NT1 is that an autoimmune response kills the orexin-producing neurons. Orexin is a neurotransmitter that plays a role in healthy sleep architecture as well as wakefulness. In theory, orexin agonists are a much more direct treatment of the underlying issue than current treatments.
So hopefully there will be some better treatments available for y'all in the next few years. May even be worth trying to find a trial for one in your area.
I was prescribed Modafinil, and while it did keep me from falling asleep, it didn't help with my wakefulness otherwise. When I had a serious crash, instead of sleeping through most of it, I would be awake through it all, with all the discomfort of the extreme fatigue and mental fog, but with no ability to fast forward time by sleeping through it. After a few months I decided it wasn't worth it.
I'm on methylphenidate right now, and while reports are that it makes CFS worse, I find it helps me to remain more aware and capable when I start getting quite sleepy, to the point where I can often wait it out rather than having to actually fall asleep. It doesn't seem to have changed the frequency of attacks nor did it prevent the really big ones, but I was able to at least work most days whereas before I was regularly too foggy to do much of anything.
The other medication my doctor suggested was Xyrem. While the research is promising for treating IH specifically, the effects and risks are worrying enough that I don't think it's worth it. It's also very expensive and it seems unlikely that my insurance would cover it, since it's off-label usage.
