Made it 4 days without sleep and then the next few days, I had managed to get around 2-3 hours of sleep throughout each night. *shrugs* Usually, I can go insane lengths on barely any sleep, but sooner or later, I'll crash and have something like 12-18 hours of sleep. I regularly run on little sleep, usually when I'm going through a major mood swing. Major bipolar disorder where I'll swing from insomnia during my manic episodes and hypersomnia during depression ones. *shrugs*
