As far as skipping breakfast goes, eat your breakfast within 30 minutes of waking up - Do not sit in bed for hours (I am guilty of this) and do not get everything else ready before breakfast.
If you eat as soon as you wake up, your metabolism gets a bit of a kickstart... If you wait and then eat, your metabolism doesn't work as fast.

Q... As far as the sleeping thing, what about not sleeping at all? xD
Pulled an all nighter two nights ago because I had probably 800+mg of caffiene that day, which I know is not healthy, dont lecture me on that
Went all day yesterday without being tired at all (Except during a meeting, but that was boredom more than anything)
