I got a question: You know how after you haven't slept for a long while (*coughs*) you get a bit of a second wind? It's not that you are any more rested or effective, but it does feel that way. Does that have to do with things like sunlight, or is it endogenous? What's the neurochemistry behind it?
Apologies from the rambling, incoherent post. Not coincidentally, I didn't get any sleep last night.
