Is it normal to not be tired after being up for 18+ hours?
I know most people stay up for 16 hours a day and sleep 8. Or they have some other hours that total to 24, and cycle with the rest of the world.
I never EVER get tired after having been up for even 18 hours. Usually I'm up for about 20-22 before I am tired enough to sleep, but then I usually feel the need to sleep for about 8-10 hours... because of this I'm always on a really messed up sleep schedule. It makes school & work very difficult, as well as planning things with friends! I'm usually sleep deprived as I try to stay on schedule with the rest of the world. Is this normal? Any advice on what could help?
