I used to run into that roadblock before. I find that what you can do is look at the ideas you started with and what you have written and then make sure that all your points are sufficiently proven. There is almost always some finer detail you can elaborate on (for instance by adding an example or two) and if it doesn't quite fit, you can delegate it to end notes or foot notes. Sometimes, it really is waste and you have to hit the deadline, but other times it can make your piece a lot more interesting.
