The normal tendency to wake up feeling refreshed and alert gets exaggerated into a sudden irresistable jolt of awakeness.
I’m pretty sure this is wrong. I’ll wake up feeling unable to go back to sleep, but not feeling well-rested and refreshed. I imagine it’s closer to a caffeine headache? (I feel tired and headachy but not groggy.) So, at least for me, this is a body clock thing, and not a transient effect.
