For sleep its something similar except the chemical has to be built up and worn off at about the same pace. Aka people that can fall asleep very fast also wake up very fast...and those like us that take forever to fall asleep also take forever to go from sleepy to awake.
With me, the time it takes to wake up seems to depend on how deep the sleep is, not how long it takes to fall asleep.
I went through one period of about ten years when I averaged about two hours of sleep a night. It would take me forever to fall asleep, but I would fully wake up to full alertness seemingly instantly.
These days it rarely takes me long to fall asleep, usually within five minutes, but it is difficult for me to wake up. If left alone, I could easily sleep twelve or more hours straight.
I think that the time it takes to fall asleep is usually, but not always, based more on habit than anything else. When I used to watch tv or read in bed, it could take hours to fall asleep. Also, if I'm worried about something, it can take a long time to fall asleep. But when I walk into the bedroom, take off my clothes, turn off the lights, and crawl into bed night after night after night after night, at about the same time every night, falling asleep rarely takes more than about five minutes. Often I'm not aware of even warming up the bed before I'm asleep.
