Get an early start, say 8am. Early enough so that you're gagging to get back to bed for the next couple of hours. Go about your business (for me it's 2hrs of classes, grab a quick bite to eat) and settle down for a nap in the early afternoon. Even if you don't manage a straightforward WILD, you'll no doubt get some sort of DILD due to being awake for a bit, kind of a big WBTB.
