One of my friends had the same experience as yours, sometimes you don't feel that you are under pressure, but it's a matter of the un-balanced hormones (according to my friend), for my friend's case, she didn't have good sleep and regular supers at that time, so don't worry just get some evening sleep and eat some good stuff lah!
I want to have evening sleep, too, but cannot in office. Take care.
