"Yeah sorry I've been so sleepy the last few times we've talked. I've been sleeping between all of my classes because I wasn't eating anything so I was really sleepy. And then I got really dehydrated and stayed up till 5:30 in the morning."
Ah, those were the days, when you just sort of experimented with your body to see how it would react to extremes. Also, is dehydration like caffeine, or speed?
