I have an off the wall idea on this (if you have not solved it yet). In people with Chronic Fatigue Syndrome, they often have a reaction of "I have to lay down NOW" It doesn't matter where they are, or what they are doing. It could be in a store, or on the sidewalk.
Anyway, the mystery of this may have to do with a PFO (Patent Ovale Foramen), a hole in your heart. Lots of people have these, but without symptoms. If the PFO is opening up on you, it can shunt unoxygenated blood back out into circulation, and straight to your brain. This can make you suddenly very tired.
If you have major headaches, it can be indication of this problem. One way to test for it, without getting invasive, is to get a hold of a finger cuff/pulse oxymeter. Check your O2 saturation for normal (96-99 %, I believe), then check it during a "sleepy episode". If the O2 saturation drops way down, like 85%, it could indicate a PFO. And that could make you sleepy all of a sudden.
The thing about PFO's is: we all (100%) have them... before we are born, because we aren't having to oxygenate our own blood. Our mommies do that for us. But, when we are born, the hole is supposed to close up, and sometimes it doesn't. (It's a flap actually) And sometimes it can reopen for various reasons.
It's probably not your case. But I think the idea is so neat, and a rough test so simple, I thought I'd share.
