Same thing went down for me yesterday. The paper was due today, and I started on it at 9:30pm. Ended up staying awake til 6:30ish to finish a completely fleshed out 6 pages of research. It's possible, but you got to remember there is no way out once you start. There shall be no breaks. No quick browse through your tumblr dashboard. Not even HB. Stock up on energy drinks or whatever to keep you awake and focused. Seriously, once you start getting some progress, you won't stop. If you don't work hard on the rough draft now, there won't be another opportunity for it. The only thing that's assured, if you slack, is a shitty grade.
