"Hypoglycemic event" sounds too damn festive, like something I should send out an Evite for ...
... instead of the confusion-inducing, sweaty, emotionally confusing, glucose-tab scarfing, guilt-laced, panic-fueled moment that it actually is.
Besides, if I sent out an invitation, someone would be there to talk me out of eating 150 carbs to treat a 40 mg/dL. And where's the fun in that? :p
