Tired, but still writing

So I've entered the phase of writing when I am so interested in what I'm doing that I wake up in the middle of the night thinking about my work. It happens rarely, I admit, and when it does happen, it is equally exciting and annoying. To be honest, I'd rather sleep and have brilliant epiphanies when I'm meant to be working. I haven't been sleeping all that well recently, so I've actually been able to work out quite a few problems with my proposal in the middle of the night. In fact, I worked out so many that I am finally able to present a complete (although rough) chapter outline, with descriptions, to my advisor later today. I'm feeling particularly proud of how much work I've gotten done this week. I'd feel prouder if my productive mood wasn't going to be interrupted by a week and a half long visit to see family. . .
