I think it is a good idea whenever you have been in a high-stress, bright-lights environment before sleeping to take a little while to wind down, in a dimly lit quiet room. Reading by an oil lamp or candle is ideal for this, maybe half an hour to an hour, however long it takes you to feel calm and slow and your eyes start getting really heavy.
Of course, staying up until 2AM is not so great, but you do what you can. Make sure you have your windows well covered so you can sleep through the morning; you'll want to be sleeping until at least 10AM to make sure you are well rested. Good luck!
