I never have trouble sleeping when I sleep. But I, like many people in this industry, don't let myself. I'll push myself to work till I'm sleeping at 2, 4, 8am... the ultimate consequences are pretty similar symptoms to those you describe, albeit self-inflicted. And the problem is that after a while it reaches the point where I don't feel "tired" during the day, but I know I'm not performing my best. Recently I'm finding my tolerance of sleeplessness much lower, and like the sibling poster I put it down to increasing age (though I'm still in my early twenties). I know the existence of 'burnout' (and all the baggage that term comes with) is debated by some, but the physical effects of not having enough rest are all too real. I know you know this already, but - sleep, people. You'll thank yourself for it.
