Things that suck: feeling your blood sugar fall out from under you while you're talking to a student. Seriously, it felt like I was fallling off a cliff.1 Yarg.
Oh, I had food handy. I slurped down an apple, then ate some lunch as soon as I got the student out of my office. It just didn't feel good at all, ya know?
Not to mother you, but do you carry snacks in your backpack, just in case? I always carry some nuts, an apple, and lunch on Friday.
