Yeah on the opposite I'd say it's pretty clear that the insomnia and poor sleep during night contributes heavily to why we are so spent and sleepy during the day. Aside from general insomnia I also had so much night terrors. Terrible nightmare, then waking up, then resuming the terrible nightmare again. Sometimes I'd try to stay awake just not to experience the night terrors. I inadvertently learned lucid dreaming to handle them.
