It's not uncommon for me, if I'm highly engaged in something, to work straight for 15-20 hours. So as a result, my wake/sleep cycle is consistently longer than 24 hours. And that has the additional benefit of frustrating geolocation.
Even so, I rarely go more than 30 hours awake. But with occasional naps, some as long as a couple hours, runs as long as a few days are not uncommon.
I take modafinil for bipolar disorder, and zolpidem for insomnia. So I can avoid many of the downsides of sleep deprivation. One cool thing about modafinil is that it increases alertness and engagement, but doesn't interfere with sleep as much as coffee and amphetamines do.
This describes me as well. Bipolar and ADHD. If I'm engaged in something I obsess over it and work 10+ hours until it's done.
It takes every other feeling away and not until I stop do other things come back (sleep fatigue, hunger, etc)
Yes, just that. I struggle a lot with getting engaged. Especially if I'm uncertain how to proceed. Or if whatever seems too difficult. Too big to imagine.
But once I do get engaged, especially if I understand (or at least, think I do) how to proceed, I won't stop until it's done.
