Separation anxiety

My book is almost ready and I am having separation issues. The publisher has set up a site for my coeditor and I to upload the chapters and I am procrastinating. I should just do it. In truth, I think it will be a huge weight lifted off my shoulders. It's been a three year long process from inception of idea, to writing the proposal, to getting scientists to contribute chapters, and finally putting the whole mammoth thing together. I don't think I'll do another one for a while. It was a lot of work. Ok, better get to it...
