Huge thanks for your dedicated replies. As I became more consciously spiritual, I noticed how I would wake up with full energy in the morning, and when I then right off went to school, literally the moment I entered the building I started yawning without end. No matter whether my day lasted until 2,4 or 6pm, at the from the first minute on I felt the deep need to go to sleep and take some rest. But to my surprise, the moment I was back at home, I was fully energized again. Now I get that pattern, but it was interesting rgeardless :)
