Eduventure: The AR Edition - School Chat

So I do this thing where I fall asleep in certain classes and I'm not sure why. It's not that the classes are boring, or because I didn't get enough sleep (although it doesn't help when it happens). I just kind of clonk out. So I try a bunch of crazy schemes that include electricity or utility knives or large quantities of stimulants (of the legal variety).

Anyone else have/had this problem?
