I am unable to take naps or fall asleep by accident. I have to be explicitly trying to sleep, and it usually takes at least half an hour to fall asleep. This holds even when I haven’t slept for over a day and I’m exhausted—I still have to give myself permission, and the process is still not fast.
I have basically the same thing, maybe a little less marked. Nap are pointless for me unless they last at least 90 minutes, because I’ll spend the first half hour or so barely dozing. I can sometimes fall asleep more quickly, though, when extremely tired.
ETA I have never fallen asleep by accident (once or twice I’ve noticed dozy sensations creeping up on me, but it’s quite rare), and I’m an extremely light sleeper.

By contrast, I am unable to fall asleep except by accident.
