On poor sleep:
I would try eating all my carbs at night before bed. The Hibernation Diet explains why this is a good idea (but I would eat starch rather than honey or high fructose sugars).
If the liver runs low on glucose during the night, adrenaline/epinephrine will kick in to increase the release of glucose and fatty acids. Adrenaline is also a stimulant and this will make you wake up, your heart to race, and to make you sweat.
Epinephrine - Wikipedia, the free encyclopedia
I suspect the epinephrine effect is also what causes the "high energy" and "euphoria" reported by people who intermittent fast. Couple this with a high stress job and bad sleeping and you have a recipe for disaster. Just sayin.
