To post stamps to dA, you can to two things. There is a bar with labels of "Note", "(Facebook Symbol) Share", "(Tumblr Symbol) Share", and "Tweet" in the top right corner of this deviation. What you do is click the arrow beside it, highlight the thumbnail link ( : thumb110504425 : with no spaces, in this case) and paste it. There also a section in the stats area with the thumb number. Just copy and paste it.
I've found I can run on very limited amounts of sleep... but only for a couple of days. How did I discover this? Tried going for four weeks of bed at midnight-ish, get up and watch DVD at 4:30 am. By the secong Friday, I needed more sleep.
One time, I stayed up late, got up early, after 2-3 hours of sleep, stayed awake (mostly) for the next 25-30 hours (possibly more). Then when I got home, I went to bed again.
At the moment, it's school holidays. I regularly stay up til 5 or 6 or even 7 am. And end up with not enough time to go to the library, since I wake up around 11-12, then go back to sleep until 2. Library is only open during the day, which is bad for night owls like me.
