that concurs with my anecdotal sample size = 1 study, where I have gone for 3.5 days without sleep before, and just keep feeling hungry and snacking every hour or so.

(for those asking what happened after 3.5 days, I basically started getting hysterical - literally just laughing at nothing - and when I was finally able to get to a bed, it took about 2 hours of staring at the ceiling before my body finally decided I was no longer under stress, and allowed me to fall asleep).
