I don't enjoy it at all, it's terrible. My body refuses to sleep at the time that it "should," so I'm laying in bed all night trying to fall asleep but remaining wide awake, then when I'm expected to be awake and productive (school when I was a teen, office job now), I'm nodding off every five seconds and struggling to keep myself focused on a task for any length of time. The times when my body uses a spike of adrenaline to kick me out of the constant state of exhaustion, I'm in extreme amounts of pain and shaking terribly.
It's slightly better now that the office job I do currently has me working 1:30pm-10pm, so I can usually sleep around the time that my body wants me to. Recently, I've been able to go to sleep around 3am and wake up at 11, but I still get those random nights where I'm still awake at 7am, and decide that there's just no point in trying to sleep anymore and just get up for the day.
I've also had a few stretches of situations kinda like
@Rose mentioned where I just fucking needed to get rent paid that week, so I would come home from the office, get ready for cam, cam all night and into the morning, then back into the office. This made me really efficient at the 10-minute nap. I'd faceplant in my jacket during down time at the office and manage to cram an hour's worth of sleep into 10 minutes, at which point I would jerk awake, shaking like a leaf and hyperventilating a little, then go back to work. I'd need another nap in a couple hours, but hey rent got paid on time and that's the important thing.
