Of the solutions I've heard, in the conversations about this going back better than a decade, this has long been my favorite.
Switching up the pace so the characters never get eight hours of peace can warp the story and quickly get you into sleep deprevation, but it's reasonable to expect that they don't get, say, a week of peace and quiet until things are under control. It puts things on a more natural timeline.
Similarly, it means that the campaign will naturally extend months, making the rise to power a little less meteoric.
It turns a five minute workday into a five minute workweek, which doesn't sound great, but it's so easy to make a week matter.
Cheers!
