Classroom coma

like a cubicle coma, when you have immense energy before class, but once you sit down, you hit the doldrums and get really sleepy. but once that bell rings and your out you gain all your energy back.

I woke up, went to the gym and hit it hard, but once i got to school, i went into a classroom coma, and found it hard to stay awake. After class, i went back into the gym and played basketball
