I barely sleep at all, getting 5 (or if I am lucky maybe 6 or 7 hours) of sleep per night. There have also been some occasional nights where I get 4 hours of sleep unfortunately also. I have tried to use melatonin sometimes but it doesn't help very much.
And then as soon as I wake up I've gotta go wageslave away at my job for like 8-10 hours each day only to go home just to eat, do errands, play vidya for a few hours, and then sleep again. Not at all worth it, but my country doesn't allow people to NEET very easily as there is really very little in the way of social support nets, so work is my only option.
