Hmm, well I don't ever do any intensive mathematics, or math at all really. But I have overcome many cerebrally intensive challenges with the below method. Work on / build things that will aid you in solving the problem. This could be organizing code, organizing notes, (reorganizing equations??), building test pages. Anything that you can think of that is intellectually simple that will aid you later when you find your motivation. Also, after an intense push for a number of hours, go outside and sit, have a coffee or beer or wine or whiskey coke for thirty minutes. Just relax, don't work. And let the most recent effort seep into your subconscious. I often find that my subconscious is better at solving these types of problems than I am.
