Is it normal to not crave sleep
Is it normal to not crave sleep, not all the time of course, but it's like... Every day when i come back home, I do the work I have to do, and I then start up the pc, and play till 4-5 AM! I wake up at around 8 AM, while not feeling that tired, the only time I feel tired is at non-work days, when I sleep untill 12 AM, I do not know if this is normal, or healthy, and I would really want some answers.
