I had a really bad speed habit a few years ago. Extremely glad I got off it. But anyway, I stayed awake for 36+ hours many many times. I've gone 4 to 5 days without sleep and barely any food or water on quite a few occasions. Your brain has no idea what it's telling itself at that point. Your psychology can easily take over your physiology and induce all kinds of symptoms whether they be psycho semantic or real. It all starts with psychological addiction. So my answer is yes it is psychologically addictive, but physical withdrawal comes from within.
