Is there such thing as sleep?

So we've tried the Sonata, didn't work. Now we ae rotating Halcion, Ativan and Alprazolam. None of them get me more than about 4 hours of sleep, the Ativan none.
I've decided sleep is over-rated, though I would dearly love some.
I've been feeling pretty funky for a while now, numbness, tingling and some foot dragging action. I guess I need to call the neuro and see what he says.
