I'm wondering if it's not just sleep deprivation but also stress and are you eating enough? Perhaps it's exhaustion and/or dehydration. Dehydration is nasty stuff. I'd say make sure to try and get enough sleep--even if that means to stop doing stuff so you can get your ass to sleep (trust me, I had to do it last year). I know that you're working hard and classes are rough, but YOU AND YOUR HEALTH is number one. REMEMBER THAT. [/stern Molly Weasley-ish mommyness]
