That stinks. Seriously! You must be pooped. I would make his bedtime an hour earlier, and I would still put him down for a nap at 1:00 or 2:00 every day. Put a few toys and books in his crib too. Tell him this is "quiet time" and that he can read, play, or sleep. He obviously won't completely understand you, but if you consistently tell him this- eventually he will!
Down time is important, too. So either he'll nap or he won't, but he'll still get time to himself. He may fuss, but I'd leave him to it. A good 45 minutes in his crib will do you both good! :)
