I don't know about OP's intentions, but I upvoted it because I think it might be useful to others. So many people (including me, until a few months ago) think that it's good to "pull all-nighters", stay awake for 20-30 hours straight if you can and finish the code (some people literally cannot stay awake for more than 20 hours. I can - I routinely stayed awake for something like 40 hours in the weekdays and then would drop dead for 15 hours).

5 or 6 months ago, I recovered my senses and changed my sleeping habits and now sleep a good 8-10 hours every day and feel I'm so much more "productive" that sometimes I feel sad about the "lost time".

So, this topic might bring others who were deluded (like me) back to sanity (or I hope so)!
